Kind is broader than kin, denoting the most general relationship, as of the whole human species in mankind, humankind, etc.; kin and kindred denote direct relationship that can be traced through either blood or marriage, preferably the former; either of these words may signify collectively all persons of the same blood or members of the same family, relatives or relations. — from kin
