Why does Child even have the family_id attribute? Can't you get the child's family through it's person (parent)? Unless the child can belong to a different family than the person, this is an unnecessary association.
Anyway, that doesn't really answer the question. accepts_nested_atrributes_for and attr_protected on the foreign keys doesn't work together. My question is: Why are you putting attr_protected on the foreign_keys? To prevent users from being able to move a child to a different parent when editing its attributes? If so, I recommend you use attr_readonly instead.
