I don't mind
Luca. It's popular in Australia at the moment, as is
Lucas (which I dislike), but it seems weird to me on little boys without Italian backgrounds.
I know. I should totally not feel that way. I think different ethnic names are anyone's game, but
Luca is that one exception for me, for no real reason at all.
I don't think it is overly effeminate.
Micah,
Judah,
Ezra, even
Sasha I find all very masculine.
