Plural of consanguinity; multiple instances or relationships of blood kinship and family descent.
From 'consanguinity' (the noun form) with the standard plural suffix '-ies'; the plural form emphasizes multiple different blood relationships or occasions of kinship.
Using the plural 'consanguinities' shows how formal English loved to discuss different types of blood relationships separately—you might have different consanguinities with your maternal versus paternal sides of the family!
