The names themselves are all very nice I think but you can definitely tell they wanted a boy! I especially like
Alexandra Rose,
Georgia Renee,
Michaela Anne and David-Peter
Andrew. The nicknames however...
Joe (though I wouldn't spell it like that)
Alex and
Charlie I have no problem with as they have a nice "tomboyish" style and they are readily accepted on girls nowadays but
Dan,
George and
Mike are just too masculine, even as nicknames, to work on girls.
