Isabeau?

I heard someone say this a few months ago and I am just not a fan of it. It sounds like a dog name to me. And I do think it would be confused and spelled wrong their whole life.

Except for the fact that [name_f]Isabeau[/name_f] is a traditional [name_m]French[/name_m] name used by people who are actually, you know, [name_m]French[/name_m].
I understand not liking the name, but all of these comments disregarding [name_f]Isabeau[/name_f] as “masculine” or incorrect in [name_m]French[/name_m] are a little annoying.
