Lovely names, used by both English and French so definitely use if you want.
However, I'm going against most people here....I do think that both are definitely French-sounding in origin (or at least sound it - not going to delve into actual name origins) and the average person will assume there is a French link somewhere in the family.
But it's not a big deal to correct if anyone asks - you just say that you liked the names! It's definitely not something that should put you off using them. "Too French" isn't a problem.
