The Answer is: a conjugal family is a family where by the
husband and the wife relationship is inward and their ties to the
extended family are voluntarily. A consanguine family is a family
of close relatives other than the parents and children.
"Conjugal" means "married". A conjugal pair is a married couple.
The word "consanguine" means "of the same blood". People who are
consanguine are decended from the same ancestor (usually within a
couple of generations). You can be both: Cleopatra and her husband
were a consanguine conjugal couple, because he was both her husband
and her brother.
