How were noblewomen named/titled in Medieval France, c. 11th century?

Question

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?

Answer 1

The French noblewomen usually were named based on where she was born, in the case of many Isabelle born in Burgundy, the first in line would be Isabelle of Burgundy, the second would be Isabelle of Dijon (or whatever town was the most populated by then/where she really was born) and so on.

In the case where one of them inherited a noble title and were left in power, like Mahaut d'Artois who became Mahaut Countess of Artois , they would use the title as long as they had it.

Most noblewomen in France were not hiding their lineage, especially to potential suitors, lying would serve no one and would most likely end in a royal decree cancelling the mariage, excommunication or worse. Most likely, they said "Emma of Blois, daughter of the Count of Blois" or stuff like that.
