I love
Mathilde, it's my favourite form of this name. Hélène and
Samuel are also really pretty.
Mina and
Raven - this sibset has quite a gothic novel-y feel to it.
Mina is fine but I prefer
Minna. While I like the meaning "raven" I probably wouldn't use the actual word. I'd rather go with Corvin,
Corbin, Corbinian or even
Raban.
Vince makes a nice nickname for
Vincent, I don't really like it as a name on its own right, though.
