Third-degree Relative
Third-degree relatives are a segment of the extended family and includes first cousins, great grandparents and great grandchildren. Third-degree relatives are generally defined by the expected amount of genetic overlap that exists between two people, with the third-degree relatives of an individual sharing approximately 12.5% of their genes. The category includes great-grandparents, great-grandchildren, grand-uncles, grand-aunts, first cousins, half-uncles, half-aunts, half-nieces and half-nephews. See also *Family * First-degree relative *Second-degree relative A second-degree relative (SDR) is someone who shares 25% of a person's genes. It includes uncles, aunts, nephews, nieces, grandparents, grandchildren, half-siblings, and double cousins. See also *Family Family (from la, familia) is a ... References Family {{society-stub ...

Extended Family
An extended family is a family that extends beyond the nuclear family of parents and their children to include aunts, uncles, grandparents, cousins or other relatives, all living nearby or in the same household. Particular forms include the stem and joint families. Description In some circumstances, the extended family comes to live either with or in place of a member of the immediate family. These families include, in one household or close proximity, relatives in addition to an immediate family. An example would be an elderly parent who moves in with his or her children due to old age. In modern Western cultures dominated by immediate family constructs, the term has come to be used generically to refer to grandparents, uncles, aunts, and cousins, whether they live together within the same household or not. However, it may also refer to a family unit in which several generations live together within a single household. In some cultures, the term is used synonymously with consang ...

Great-grandparents
Grandparents, individually known as grandmother and grandfather, are the parents of a person's father or mother – paternal or maternal. Every sexually-reproducing living organism who is not a genetic chimera has a maximum of four genetic grandparents, eight genetic great-grandparents, sixteen genetic great-great-grandparents, thirty-two genetic great-great-great-grandparents, sixty-four genetic great-great-great-great grandparents, etc. In the history of modern humanity, around 30,000 years ago, the number of modern humans who lived to be a grandparent increased. It is not known for certain what spurred this increase in longevity but largely results in the improved medical technology and living standard, but it is generally believed that a key consequence of three generations being alive together was the preservation of information which could otherwise have been lost; an example of this important information might have been where to find water in times of drought. In cases ...

Great-grandchildren
Family (from la, familia) is a group of people related either by consanguinity (by recognized birth) or affinity (by marriage or other relationship). The purpose of the family is to maintain the well-being of its members and of society. Ideally, families offer predictability, structure, and safety as members mature and learn to participate in the community. Historically, most human societies use family as the primary locus of attachment, nurturance, and socialization. Anthropologists classify most family organizations as matrifocal (a mother and her children), patrifocal (a father and his children), conjugal (a wife, her husband, and children, also called the nuclear family), avuncular (a man, his sister, and her children), or extended (in addition to parents and children, may include grandparents, aunts, uncles, or cousins). The field of genealogy aims to trace family lineages through history. The family is also an important economic unit studied in family economics. The ...

Great-uncles
An uncle is usually defined as a male relative who is a sibling of a parent or married to a sibling of a parent. Uncles who are related by birth are second-degree relatives. The female counterpart of an uncle is an aunt, and the reciprocal relationship is that of a nephew or niece. The word comes from la, avunculus, the diminutive of ''avus'' (grandfather), and is a family relationship within an extended or immediate family. In some cultures and families, children may refer to the cousins of their parents as uncle (or aunt). It is also used as a title of respect for older relatives, neighbours, acquaintances, family friends, and even total strangers in some cultures, for example Aboriginal Australian elders. Using the term in this way is a form of fictive kinship. Any social institution where a special relationship exists between a man and his sisters' children is known as an avunculate (or avunculism or avuncularism). This relationship can be formal or informal, depending ...

First Cousins
Most generally, in the lineal kinship system used in the English-speaking world, a cousin is a type of familial relationship in which two relatives are two or more familial generations away from their most recent common ancestor. Commonly, "cousin" refers to a first cousin – a relative of the same generation whose most recent common ancestor with the subject is a grandparent. Degrees and removals are separate measures used to more precisely describe the relationship between cousins. ''Degree'' measures the separation, in generations, from the most recent common ancestor(s) to a parent of one of the cousins (whichever is closest), while ''removal'' measures the difference in generations between the cousins themselves, relative to their most recent common ancestor(s). To illustrate usage, a second cousin is a cousin with a ''degree'' of two; there are three (not two) generations from the common ancestor(s). When the degree is not specified, first cousin is assumed. A cousin ...

Half-uncle
An uncle is usually defined as a male relative who is a sibling of a parent or married to a sibling of a parent. Uncles who are related by birth are second-degree relatives. The female counterpart of an uncle is an aunt, and the reciprocal relationship is that of a nephew or niece. The word comes from la, avunculus, the diminutive of ''avus'' (grandfather), and is a family relationship within an extended or immediate family. In some cultures and families, children may refer to the cousins of their parents as uncle (or aunt). It is also used as a title of respect for older relatives, neighbours, acquaintances, family friends, and even total strangers in some cultures, for example Aboriginal Australian elders.

Half-niece
In the lineal kinship system used in the English-speaking world, a niece or nephew is a child of the subject's sibling or sibling-in-law. The converse relationship, the relationship from the niece or nephew's perspective, is that of an aunt or uncle. A niece is female and a nephew is male. The term nibling has been used in place of the common, gender-specific terms in some specialist literature. As aunt/uncle and niece/nephew are separated by one generation, they are an example of a second-degree relationship. They are 25% related by blood. Lexicology The word nephew is derived from the French word ''neveu'' which is derived from the Latin ''nepos''. The term ''nepotism'', meaning familial loyalty, is derived from this Latin term. ''Niece'' entered Middle English from the Old French word ''nece'', which also derives from Latin ''nepotem''. The word ''nibling'' is a neologism suggested by Samuel Martin (linguist), Samuel Martin in 1951 as a cover term for "nephew o ...

First-degree Relative
A first-degree relative (FDR) is a person's parent (father or mother), full sibling (brother or sister) or child. It constitutes a category of family members that largely overlaps with the term nuclear family, but without spouses. If the persons are related by blood, the first degree relatives share approximately 50% of their genes. First-degree relatives are a common measure used to diagnose risks for common diseases by analyzing family history.
