Help with Names

Robin
We know what we want for a boy, but are struggling with a girl. We don't like anything too frilly or overly feminine. Unisex names are definitely on the plus side, but we are a little open if it's a strong name.
Right now the top contenders are:
Marley
Andi
Any good thoughts for us? We are so in love with our boy name and just aren't feeling girl names as much although we do like our picks.
