Familial

adj. of a family; occurring in or characteristic of a family

Family is a Western term used to have denote a domestic group of people, or a number of domestic groups linked through descent (demonstrated or stipulated) from a common ancestor, marriage or adoption.A family may be defined specifically as a group of people affiliated by consanguinity, affinity, and co-residence. Although the concept of consanguinity originally referred to relations by blood, many anthropologists argue that the notion of "blood" must be understood metaphorically; some argue that there are many non-Western societies where family is understood through other concepts rather than "blood"
