In the context of human society, a family (from Latin: familia) is a group of people related either by consanguinity (by recognized birth), affinity (by marriage or other relationship), or co-residence (as implied by the etymology of the English word "family") or some combination of these.  Members of the immediate family may include spouses, parents, brothers, sisters, sons, and daughters.  Members of the extended family may include grandparents, aunts, uncles, cousins, nephews, nieces, and siblings-in-law.  Sometimes these are also considered members of the immediate family, depending on an individual's specific relationship with them.
