I enjoy these male names on girls (in theory if not in practice):
Mike EddieJakeQuentin EzraElijahIsaiahGlennLevi (I've been watching a show where this is the name given to a character with no gender, but the voice is very feminine, so now
Levi feels feminine to me)
Nolan (could be the next
Logan, I don't see why not)
TheoChristian (this wasn't always a male name but it seems very male nowadays so it counts)
AustinRudyMaxDavisWillem and
Willis
Vice Versa:
