A family history may include additional biographical information, family traditions, and the like.
The pursuit of family history and origins tends to be shaped by several motives, including the desire to carve out a place for one's family in the larger historical picture, a sense of responsibility to preserve the past for

Overview
Amateur genealogists typically pursue their own ancestry and that of their spouses. Professional genealogists may also conduct research for others, publish books on genealogical methods, teach, or produce their own databases. They may work for companies that provide software or produce materials of use to other professionals and to amateurs. Both try to understand not just where and when people lived but also their lifestyles, biographies, and motivations. This often requires—or leads to—knowledge of antiquated laws, old political boundaries, migration trends, and historical socioeconomic or religious conditions.
Genealogists sometimes specialize in a particular group, e.g., a

Genealogists and family historians often join
family history societies, where novices can learn from more experienced researchers. Such societies generally serve a specific geographical area. Their members may also index records to make them more accessible or engage in advocacy and other efforts to preserve public records and cemeteries. Some schools engage students in such projects as a means to reinforce lessons regarding immigration and history. Other benefits include family medical histories for families with serious medical conditions that are hereditary.
The terms "genealogy" and "family history" are often used synonymously, but some entities offer a slight difference in definition. The

Motivation
Individuals conduct genealogical research for a number of reasons.
Personal or medical interest
Private individuals research genealogy out of curiosity about their heritage. This curiosity can be particularly strong among those whose family histories were lost or unknown due to, for example,
adoption

United States
Genealogical research in the United States was first systematized in the early 19th century, especially by
John Farmer (1789–1838).
[François Weil, ''Family Trees: A History of Genealogy in America'' (Cambridge, Mass.: Harvard University Press, 2013), Chapter 1.] Before Farmer's efforts, tracing one's genealogy was seen as an attempt by the American colonists to secure a measure of social standing, an aim that was counter to the new republic's egalitarian, future-oriented ideals (as outlined in the

).
As Fourth of July celebrations commemorating the Founding Fathers and the heroes of the Revolutionary War became increasingly popular, however, the pursuit of "antiquarianism", which focused on local history, became acceptable as a way to honor the achievements of early Americans. Farmer capitalized on the acceptability of antiquarianism to frame genealogy within the early republic's ideological framework of pride in one's American ancestors. He corresponded with other antiquarians in New England, where antiquarianism and genealogy were well established, and became a coordinator, booster, and contributor to the growing movement. In the 1820s, he and fellow antiquarians began to produce genealogical and antiquarian tracts in earnest, slowly gaining a devoted audience among the American people. Though Farmer died in 1839, his efforts led to the creation of the

Research process
Genealogical research is a complex process that uses historical records and sometimes genetic analysis to demonstrate kinship. Reliable conclusions are based on the quality of sources (ideally, original records), the information within those sources, (ideally, primary or firsthand information), and the evidence that can be drawn (directly or indirectly), from that information. In many instances, genealogists must skillfully assemble indirect or
circumstantial evidence to build a case for identity and kinship. All evidence and conclusions, together with the documentation that supports them, is then assembled to create a cohesive genealogy or

, which involves examining and evaluating historical records for evidence about ancestors and other relatives, their kinship ties, and the events that occurred in their lives. As a rule, genealogists begin with the present and work backwards in time. Historical, social, and family context is essential to achieving correct identification of individuals and relationships. Source citation is also important when conducting genealogical research.

Genealogical societies are almost exclusively staffed by volunteers and may offer a broad range of services, including maintaining libraries for members' use, publishing newsletters, providing research assistance to the public, offering classes or seminars, and organizing record preservation or transcription projects.
Software
Genealogy software is used to collect, store, sort, and display genealogical data. At a minimum, genealogy software accommodates basic information about individuals, including births, marriages, and deaths. Many programs allow for additional biographical information, including occupation, residence, and notes, and most also offer a method for keeping track of the sources for each piece of evidence.
Most programs can generate basic kinship charts and reports, allow for the import of digital photographs and the export of data in the

Records and documentation
Genealogists use a wide variety of records in their research. To effectively conduct genealogical research, it is important to understand how the records were created, what information is included in them, and how and where to access them.

Indexing ancestral information
Indexing is the process of transcribing parish records, city vital records, and other reports, to a digital database for searching. Volunteers and professionals participate in the indexing process. Since 2006, the microfilm in the FamilySearch granite mountain vault is in the process of being digitally scanned, available online, and eventually indexed.
For example, after the 72-year legal limit for releasing personal information for the
United States Census was reached in 2012, genealogical groups cooperated to index the 132 million residents registered in the
1940 United States Census.
Between 2006 and 2012, the FamilySearch indexing effort produced more than 1 billion searchable records.
Record loss and preservation
Sometimes genealogical records are destroyed, whether accidentally or on purpose. In order to do thorough research, genealogists keep track of which records have been destroyed so they know when information they need may be missing. Of particular note for North American genealogy is the
1890 United States Census, which was destroyed in a fire in 1921. Although fragments survive, most of the 1890 census no longer exists. Those looking for genealogical information for families that lived in the United States in 1890 must rely on other information to fill that gap.
War is another cause of record destruction. During World War II, many European records were destroyed.

destroyed genealogy books kept by families.
Often records are destroyed due to accident or neglect. Since genealogical records are often kept on paper and stacked in high-density storage, they are prone to fire, mold, insect damage, and eventual disintegration. Sometimes records of genealogical value are deliberately destroyed by governments or organizations because the records are considered to be unimportant or a privacy risk. Because of this, genealogists often organize efforts to preserve records that are at risk of destruction. FamilySearch has an ongoing program that assesses what useful genealogical records have the most risk of being destroyed, and sends volunteers to digitize such records.

Types of information
Genealogists who seek to reconstruct the lives of each ancestor consider all historical information to be "genealogical" information. Traditionally, the basic information needed to ensure correct identification of each person are place names, occupations,
family name
In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community.
Practices vary by culture. The family name may be placed at either the start of a person's full name ...
s, first names, and dates. However, modern genealogists greatly expand this list, recognizing the need to place this information in its historical context in order to properly evaluate genealogical evidence and distinguish between same-name individuals. A great deal of information is available for British ancestry with growing resources for other ethnic groups.
Family names
Family names are simultaneously one of the most important pieces of genealogical information, and a source of significant confusion for researchers.
In many cultures, the name of a person refers to the family to which they belongs. This is called the ''family name'', ''surname'', or ''last name''.
Patronymic
A patronymic, or patronym, is a component of a personal name based on the given name of one's father, grandfather (avonymic), or an earlier male ancestor.
Patronymics are still in use, including mandatory use, in many countries worldwide, alt ...
s are names that identify an individual based on the father's name. For example, Marga Olafsdottir is Marga, daughter of Olaf, and Olaf Thorsson is Olaf, son of Thor. Many cultures used patronymics before surnames were adopted or came into use. The Dutch in New York, for example, used the patronymic system of names until 1687 when the advent of English rule mandated surname usage. In Iceland, patronymics are used by a majority of the population. In Denmark and Norway patronymics and farm names were generally in use through the 19th century and beyond, though surnames began to come into fashion toward the end of the 19th century in some parts of the country. Not until 1856 in Denmark and 1923 in Norway were there laws requiring surnames.
The transmission of names across generations, marriages and other relationships, and immigration may cause difficulty in genealogical research. For instance, women in many cultures have routinely used their spouse's surnames. When a woman remarried, she may have changed her name and the names of her children; only her name; or changed no names. Her birth name (
maiden name
When a person (traditionally the wife in many cultures) assumes the family name of their spouse, in some countries that name replaces the person's previous surname, which in the case of the wife is called the maiden name ("birth name" is also use ...
) may be reflected in her children's middle names; her own middle name; or dropped entirely. Children may sometimes assume stepparent, foster parent, or adoptive parent names. Because official records may reflect many kinds of surname change, without explaining the underlying reason for the change, the correct identification of a person recorded identified with more than one name is challenging. Immigrants to America often Americanized their names.
Surname data may be found in trade directories, census returns, birth, death, and marriage records.
Given names

is very common. For example, Beth, Lizzie or Betty are all common for Elizabeth, and Jack, John and Jonathan may be interchanged.
Middle names provide additional information. Middle names may be inherited, follow naming customs, or be treated as part of the family name. For instance, in some Latin cultures, both the mother's family name and the father's family name are used by the children.
Historically, naming traditions existed in some places and cultures. Even in areas that tended to use naming conventions, however, they were by no means universal. Families may have used them some of the time, among some of their children, or not at all. A pattern might also be broken to name a newborn after a recently deceased sibling, aunt or uncle.
An example of a naming tradition from England, Scotland and Ireland:
Another example is in some areas of Germany, where siblings were given the same first name, often of a favourite saint or local nobility, but different second names by which they were known (''Rufname''). If a child died, the next child of the same gender that was born may have been given the same name. It is not uncommon that a list of a particular couple's children will show one or two names repeated.
Personal names have periods of popularity, so it is not uncommon to find many similarly named people in a generation, and even similarly named families; e.g., "William and Mary and their children David, Mary, and John".
Many names may be identified strongly with a particular gender; e.g., William for boys, and Mary for girls. Others may be
ambiguous, e.g., Lee, or have only slightly variant spellings based on gender, e.g., Frances (usually female) and Francis (usually male).
Place names
While the locations of ancestors' residences and life events are core elements of the genealogist's quest, they can often be confusing. Place names may be subject to variant spellings by partially literate scribes. Locations may have identical or very similar names. For example, the village name
Brockton occurs six times in the border area between the English counties of

Staffordshire

. Shifts in political borders must also be understood. Parish, county, and national borders have frequently been modified. Old records may contain references to farms and villages that have ceased to exist. When working with older records from Poland, where borders and place names have changed frequently in past centuries, a source with maps and sample records such as ''
'' can be invaluable.
Available sources may include vital records (civil or church registration), censuses, and tax assessments. Oral tradition is also an important source, although it must be used with caution. When no source information is available for a location, circumstantial evidence may provide a probable answer based on a person's or a family's place of residence at the time of the event.
Maps and gazetteers are important sources for understanding the places researched. They show the relationship of an area to neighboring communities and may be of help in understanding migration patterns.

Dates
It is wise to exercise extreme caution with dates. Dates are more difficult to recall years after an event, and are more easily mistranscribed than other types of genealogical data.
[Peter R. Knights, "The Accuracy of Age Reporting in the Manuscript Federal Census of 1850 and 1860," ''Historical Methods Newsletter,'' 4 (1971), 79–83; Karen Oppenheim Mason and Lisa G. Cope, "Sources of Age and Date-of-Birth Misreporting in the 1900 U.S. Census," ''Demography'' vol. 24, no. 4 (Nov., 1987), pp. 563–573.] Therefore, one should determine whether the date was recorded at the time of the event or at a later date. Dates of birth in vital records or civil registrations and in church records at baptism are generally accurate because they were usually recorded near the time of the event. Family Bibles are often a source for dates, but can be written from memory long after the event. When the same ink and handwriting is used for all entries, the dates were probably written at the same time and therefore will be less reliable since the earlier dates were probably recorded well after the event. The publication date of the Bible also provides a clue about when the dates were recorded since they could not have been recorded at any earlier date.
People sometimes reduce their age on marriage, and those under "full age" may increase their age in order to marry or to join the armed forces.
Census
A census is the procedure of systematically acquiring, recording and calculating information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses incl ...
returns are notoriously unreliable for ages or for assuming an approximate death date. Ages over 15 in the
1841 census in the UK are rounded down to the next lower multiple of five years.
Although baptismal dates are often used to approximate birth dates, some families waited years before baptizing children, and adult baptisms are the norm in some religions. Both birth and marriage dates may have been adjusted to cover for pre-wedding pregnancies.

25 March; this was changed to 1 January. Many other European countries had already made the calendar changes before England had, sometimes centuries earlier. By 1751 there was an 11-day discrepancy between the date in England and the date in other European countries.

The
French Republican Calendar or French Revolutionary Calendar was a calendar proposed during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days in 1871 in Paris. Dates in official records at this time use the revolutionary calendar and need "translating" into the Gregorian calendar for calculating ages etc. There are various websites which do this.
Occupations
Occupational information may be important to understanding an ancestor's life and for distinguishing two people with the same name. A person's occupation may have been related to his or her social status, political interest, and migration pattern. Since skilled trades are often passed from father to son, occupation may also be indirect evidence of a family relationship.
It is important to remember that a person may change occupations, and that titles change over time as well. Some workers no longer fit for their primary trade often took less prestigious jobs later in life, while others moved upwards in prestige. Many unskilled ancestors had a variety of jobs depending on the season and local trade requirements. Census returns may contain some embellishment; e.g., from

Reliability of sources
Information found in historical or genealogical sources can be unreliable and it is good practice to evaluate all sources with a critical eye. Factors influencing the reliability of genealogical information include: the knowledge of the informant (or writer); the bias and mental state of the informant (or writer); the passage of time and the potential for copying and compiling errors.
The quality of census data has been of special interest to historians, who have investigated reliability issues.
Knowledge of the informant
The informant is the individual who provided the recorded information. Genealogists must carefully consider who provided the information and what they knew. In many cases the informant is identified in the record itself. For example, a death certificate usually has two informants: a physician who provides information about the time and cause of death and a family member who provides the birth date, names of parents, etc.
When the informant is not identified, one can sometimes deduce information about the identity of the person by careful examination of the source. One should first consider who was alive (and nearby) when the record was created. When the informant is also the person recording the information, the handwriting can be compared to other handwriting samples.
When a source does not provide clues about the informant, genealogists should treat the source with caution. These sources can be useful if they can be compared with independent sources. For example, a census record by itself cannot be given much weight because the informant is unknown. However, when censuses for several years concur on a piece of information that would not likely be guessed by a neighbor, it is likely that the information in these censuses was provided by a family member or other informed person. On the other hand, information in a single census cannot be confirmed by information in an undocumented compiled genealogy since the genealogy may have used the census record as its source and might therefore be dependent on the same misinformed individual.
Motivation of the informant
Even individuals who had knowledge of the fact, sometimes intentionally or unintentionally provided false or misleading information. A person may have lied in order to obtain a government benefit (such as a military pension), avoid taxation, or cover up an embarrassing situation (such as the existence of a non-marital child). A person with a distressed state of mind may not be able to accurately recall information. Many genealogical records were recorded at the time of a loved one's death, and so genealogists should consider the effect that grief may have had on the informant of these records.
The effect of time
The passage of time often affects a person's ability to recall information. Therefore, as a general rule, data recorded soon after the event are usually more reliable than data recorded many years later. However, some types of data are more difficult to recall after many years than others. One type especially prone to recollection errors is dates. Also the ability to recall is affected by the significance that the event had to the individual. These values may have been affected by cultural or individual preferences.
Copying and compiling errors
Genealogists must consider the effects that copying and compiling errors may have had on the information in a source. For this reason, sources are generally categorized in two categories: original and derivative. An original source is one that is not based on another source. A derivative source is information taken from another source. This distinction is important because each time a source is copied, information about the record may be lost and errors may result from the copyist misreading, mistyping, or miswriting the information. Genealogists should consider the number of times information has been copied and the types of derivation a piece of information has undergone. The types of derivatives include: photocopies, transcriptions, abstracts, translations, extractions, and compilations.
In addition to copying errors, compiled sources (such as published genealogies and online pedigree databases) are susceptible to misidentification errors and incorrect conclusions based on circumstantial evidence. Identity errors usually occur when two or more individuals are assumed to be the same person. Circumstantial or indirect evidence does not explicitly answer a genealogical question, but either may be used with other sources to answer the question, suggest a probable answer, or eliminate certain possibilities. Compilers sometimes draw hasty conclusions from circumstantial evidence without sufficiently examining all available sources, without properly understanding the evidence, and without appropriately indicating the level of uncertainty.
Primary and secondary sources
In genealogical research, information can be obtained from primary or secondary sources. Primary sources are records that were made at the time of the event, for example a death certificate would be a primary source for a person's death date and place. Secondary sources are records that are made days, weeks, months, or even years after an event.
Standards and ethics
Organizations that educate and certify genealogists have established standards and ethical guidelines they instruct genealogists to follow.
Research standards
Genealogy research requires analyzing documents and drawing conclusions based on the evidence provided in the available documents. Genealogists need standards to determine whether or not their evaluation of the evidence is accurate. In the past, genealogists in the United States borrowed terms from
judicial law to examine evidence found in documents and how they relate to the researcher's conclusions. However, the differences between the two disciplines created a need for genealogists to develop their own standards. In 2000, the
Board for Certification of Genealogists published their first manual of standards. The
Genealogical Proof Standard created by the Board for Certification of Genealogists is widely distributed in seminars, workshops, and educational materials for genealogists in the United States. Other genealogical organizations around the world have created similar standards they invite genealogists to follow. Such standards provide guidelines for genealogists to evaluate their own research as well as the research of others.
Standards for genealogical research include:
* Clearly document and organize findings.
* Cite all sources in a specific manner so that others can locate them and properly evaluate them.
* Locate all available sources that may contain information relevant to the research question.
* Analyze findings thoroughly, without ignoring conflicts in records or negative evidence.
* Rely on original, rather than derivative sources, wherever possible.
* Use logical reasoning based on reliable sources to reach conclusions.
* Acknowledge when a specific conclusion is only "possible" or "probable" rather than "proven".
* Acknowledge that other records that have not yet been discovered may overturn a conclusion.
Ethical guidelines
Genealogists often handle sensitive information and share and publish such information. Because of this, there is a need for ethical standards and boundaries for when information is too sensitive to be published. Historically, some genealogists have fabricated information or have otherwise been untrustworthy. Genealogical organizations around the world have outlined ethical standards as an attempt to eliminate such problems. Ethical standards adopted by various genealogical organizations include:
* Respect copyright laws
* Acknowledge where one consulted another's work and do not plagiarize the work of other researchers.
* Treat original records with respect and avoid causing damage to them or removing them from repositories.
* Treat archives and archive staff with respect.
* Protect the privacy of living individuals by not publishing or otherwise disclosing information about them without their permission.
* Disclose any conflicts of interest to clients.
* When doing paid research, be clear with the client about scope of research and fees involved.
* Do not fabricate information or publish false or unproven information as proven.
* Be sensitive about information found through genealogical research that may make the client or family members uncomfortable.
In 2015, a committee presented standards for
genetic genealogy at the Salt Lake Institute of Genealogy. The standards emphasize that genealogists and testing companies should respect the privacy of clients and recognize the limits of DNA tests. It also discusses how genealogists should thoroughly document conclusions made using DNA evidence.
