I don't like most month names. None that end in -ary or -er. The only one's I like is
May,
June,
April, and
August (all on girls) I know
August is on here as a boy name and
Augusta (which I find hideous)is the girl name but I know a girl
August and I think it sounds girly with all the other month names.
Anyway not a fan of January but it isn't as bad as other month names (I see you have
September below, that's way worse)
Only feminine though.
NN -
Jan,
Ari,
Ann,
Jana
Don't like Natane - looks like a mispelled
Nathan to me.
