Logically, if she's a princess, her mother was a high-ranking noble was was married to her father, not a noble hunter. I think you get your *caste* from your same sex parent, but it makes sense to me the children of the same caste would go to the father's house. Or her mother was a closely related Aeducan cousin. DA lore seems to have a dim view of cousin-marriage, though, so I go with the idea that her mother was a Dace or a Helmi or something similar, I high ranked noble.
