Not proof, but "the family" is recognised as really important in international law.
They don't define a family as one male adult, one female adult, and some children by birth. So, personally, I use a broad definition of family that includes homosexuals and fostering and polyamory, while rejecting stuff like forced marriage or child marriage.
