I was reading through some articles on Wikipedia and long story short I ended up reading about 11th century dukes of France. I noticed that a lot of their wives had names such as, e.g. Adelaide of Aquitaine, in which Aquitaine is the duchy their father is from, and not their husband. That's fine I guess but wouldn't it have been confusing? If you told someone that a woman was Emma of Blois, how would they know who her husband was and what duchy she is a duchess of now that she's married. I know that nowadays a woman is her own person independent of her husband but back then that really wasn't the case, and I just found it really strange.
Tl:dr- Were women really named after their fathers, even in marriage, or were they named after their husbands and are now being "re-named" by historians?
