This might help a little.

In Japan, the upper class have used a complex system that involves Branch families. This includes both blood relatives in the direct family (the Washuu), as well as lesser families (cousins, other extended family), and people brought into the family through adoption or marriage.

Adoption in this case means both our traditional idea of a child being adopted by parents, and also cases of adults or even entire families being legally adopted into a family/clan. For example, Kureo Mado was adopted into the Mado family and took his wife's name upon marriage.

So the human women would be adopted or married into the Washuu Clan, assigned to Branch families if they were not a formal wife of the main Washuu line. (Iyo Washuu versus the various Garden wombs.)
