One-name Study
A one-name study is a project researching a specific surname, as opposed to a particular pedigree (ancestors of one person) or descendancy ( descendants of one person or couple). Some people who research a specific surname may restrict their research geographically and chronologically, perhaps to one country and time period, while others may collect all occurrences world-wide for all time. A one-name study is not limited to persons who are related biologically. Studies may have a number of family trees which have no link with each other. Findings from a one-name study are useful to genealogists. Onomasticians, who study the etymology, meaning and geographic origin of names, also draw on the macro perspective provided by a one-name study. Scope Many people conducting family history, genealogical or onomastic research may conduct a one-name study of a surname in a given period or locality quite informally. A full one-name study can be daunting, particularly if the surname i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surname
In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several given names and surnames are possible in the full name. In modern times most surnames are hereditary, although in most countries a person has a right to name change, change their name. Depending on culture, the surname may be placed either at the start of a person's name, or at the end. The number of surnames given to an individual also varies: in most cases it is just one, but in Portuguese-speaking countries and many Spanish-speaking countries, two surnames (one inherited from the mother and another from the father) are used for legal purposes. Depending on culture, not all members of a family unit are required to have identical surnames. In some countries, surnames are modified depending on gender and family membership status of a person.

Genealogy
Genealogy () is the study of families, family history, and the tracing of their lineages. Genealogists use oral interviews, historical records, genetic analysis, and other records to obtain information about a family and to demonstrate kinship and pedigrees of its members. The results are often displayed in charts or written as narratives. The field of family history is broader than genealogy, and covers not just lineage but also family and community history and biography. The record of genealogical work may be presented as a "genealogy", a "family history", or a " family tree". In the narrow sense, a "genealogy" or a " family tree" traces the descendants of one person, whereas a "family history" traces the ancestors of one person, but the terms are often used interchangeably. 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 des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extinction Of Surnames
Extinction is the termination of an organism by the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover. As a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, and mammoths. Through evolution, species arise through the process of speciation. Species become extinct when they are no longer able to survive in changing conditions or against superior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Federation Of Family History Societies
previously the Federation of Family History Societies, also known as The Federation, is a United Kingdom-based charitable organisation. In 2019 it rebranded to the Family History Federation. Its stated principal aims are "to co-ordinate and assist the work of societies or other bodies interested in family history, genealogy and heraldry; to foster the spirit of mutual co-operation, by sponsoring projects in these fields". Its membership consists of over 170 family history societies and similar genealogical organisations. It publishes The National Burial Index from data supplied largely by family history societies. In January 2014, The National Archives put online the digitised records of over 8,000 individuals seeking exemption from conscription into the army in Middlesex during the First World War. The Federation assisted in funding this exercise. In the same month, The National Archives announced work to accelerate progress with the revision of the Manorial Documents Registe ...

Guild Of One-Name Studies
The Guild of One-Name Studies is a UK-based charitable organisation A charitable organization or charity is an organization whose primary objectives are philanthropy and social well-being (e.g. educational, Religion, religious or other activities serving the public interest or common good). The legal definitio ... founded in 1979 for one-name study, one-name studies. History The Guild developed as an offshoot of the Federation of Family History Societies. The FFHS was founded on 8 June 1974. By 1977 one-third of the members of the FFHS were one-name societies, and a sub-committee was set up to address the needs of this group. Among its duties was the generation of a Register of Surnames which were being comprehensively studied. The first one-name conference was held at the Grand Hotel in Leicester from 13 to 14 May 1978. Sixty-six participants attended the inaugural conference. A formal resolution was carried unanimously to establish a Guild of individuals engaged in one ...

Data Set
A data set (or dataset) is a collection of data. In the case of tabular data, a data set corresponds to one or more table (database), database tables, where every column (database), column of a table represents a particular Variable (computer science), variable, and each row (database), row corresponds to a given Record (computer science), record of the data set in question. The data set lists values for each of the variables, such as for example height and weight of an object, for each member of the data set. Data sets can also consist of a collection of documents or files. In the open data discipline, a dataset is a unit used to measure the amount of information released in a public open data repository. The European data.europa.eu portal aggregates more than a million data sets. Properties Several characteristics define a data set's structure and properties. These include the number and types of the attributes or variables, and various statistical measures applicable to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stoke-on-Trent
Stoke-on-Trent (often abbreviated to Stoke) is a city and Unitary authorities of England, unitary authority area in Staffordshire, England. It has an estimated population of 259,965 as of 2022, making it the largest settlement in Staffordshire and one of the largest cities of the Midlands. Stoke is surrounded by the towns of Newcastle-under-Lyme, Alsager, Kidsgrove and Biddulph, which form a conurbation around the city. The city is wikt:polycentric, polycentric, formed from Federation of Stoke-on-Trent, the federation of six towns in 1910. It took its name from the town of Stoke-upon-Trent where the main centre of government and the principal Stoke-on-Trent railway station, railway station in the district were located.

Genealogical DNA Test
A genealogical DNA test is a DNA-based Genetic testing, genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnicity, ethnic mixture of an individual. Since different testing companies use different ethnic reference groups and different matching algorithms, ethnicity estimates for an individual vary between tests, sometimes dramatically. Three principal types of genealogical DNA tests are available, with each looking at a different part of the genome and being useful for different types of genealogical research: Genealogical DNA test#Autosomal DNA (atDNA) testing, autosomal (atDNA), Genealogical DNA test#Mitochondrial DNA (mtDNA) testing, mitochondrial (mtDNA), and Genealogical DNA test#Y-chromosome (Y-DNA) testing, Y-chromosome (Y-DNA). Autosomal tests may result in a large number of DNA matches to both males and females who have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surname DNA Project
A surname DNA project is a genetic genealogy project which uses genealogical DNA tests to trace male lineage. In most cultures, there are few or no matrilineal surnames, or matrinames, so there are still few or no ''matrilineal'' surname projects. However, DNA tests are equally important for the two sexes (see genealogical DNA test). Because surnames are passed down from father to son in many cultures (''patrilineal''), and Y-chromosomes (Y-DNA) are passed from father to son with a predictable rate of mutation, people with the same surname can use genealogical DNA testing to determine if they share a Most recent common ancestor, common ancestor within recent history. When two males share a surname, a test of their Y-chromosome markers will determine either that they are not related, or that they are related. If they are related, the number of markers tested and the number of matches at those markers determines the range of generations until their most recent common ancestor (MRC ...

Relational Database
A relational database (RDB) is a database based on the relational model of data, as proposed by E. F. Codd in 1970. A Relational Database Management System (RDBMS) is a type of database management system that stores data in a structured format using rows and columns. Many relational database systems are equipped with the option of using SQL (Structured Query Language) for querying and updating the database. History The concept of relational database was defined by E. F. Codd at IBM in 1970. Codd introduced the term ''relational'' in his research paper "A Relational Model of Data for Large Shared Data Banks". In this paper and later papers, he defined what he meant by ''relation''. One well-known definition of what constitutes a relational database system is composed of Codd's 12 rules. However, no commercial implementations of the relational model conform to all of Codd's rules, so the term has gradually come to describe a broader class of database systems, which at a ...

Screen Scraping
Data scraping is a technique where a computer program extracts data from human-readable output coming from another program. Description Normally, data transfer between programs is accomplished using data structures suited for automated processing by computers, not people. Such interchange formats and protocols are typically rigidly structured, well-documented, easily parsed, and minimize ambiguity. Very often, these transmissions are not human-readable at all. Thus, the key element that distinguishes data scraping from regular parsing is that the data being consumed is intended for display to an end-user, rather than as an input to another program. It is therefore usually neither documented nor structured for convenient parsing. Data scraping often involves ignoring binary data (usually images or multimedia data), display formatting, redundant labels, superfluous commentary, and other information which is either irrelevant or hinders automated processing. Data scraping is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
