Etymology
From French familial (“relating to a family; familial”), from Latin familia (“family (in the sense of the slaves working for a household); household”) (from famulus (“servant; slave”), ultimately from Proto-Indo-European *dʰh₁-m-eló-, from *dʰeh₁- (“to do, place, put”)) + French -al (adjective-forming suffix) (from Latin -ālis, from Proto-Indo-European *-li-). By surface analysis, family + -al. Piecewise doublet of familiar.
