It's used as a girl's name here but
Janne is not listed by BtN.
Janne is also pronounced very dutch, I don't know if you know what I mean, but it's not a 'hard' J, as in
Jenna, but a 'soft' one; and it sounds like Jan-nuh.
But I like
Kyra and
Hannah also, so it's very hard to decide which one I like best.
Janne is less popular here in Holland.
I'm not pregnant btw, just trying to figure out which name will be my favorite name.
