Blood, relative  (BLOOD, relative)

Persons related through common descent1 from the same progenitor2 or ancestor2 are called blood relatives3 or genetic relatives3. The term kin3 is also used. The degree of relationship4 is generally computed by reference to the number of steps which are necessary before a common ancestor is reached, but there are many different methods of computation. The fundamental relation in each of these steps is the filial relation5 (112-6* and 112-7*) of child to parent, which is the reciprocal of parenthood6(112-2*) i. e., the relation of a couple or of a father or mother to offspring7or progeny7. Blood relationship must be distinguished from affinal relationship8 or relationship by marriage8, which marriage establishes between one spouse and the kin of the other.
