I'm not really sure but I suggest something extremely feminine. Our DD is named Peyton and we chose Rosalie (which actually honors three different family members through Rose and Leigh). We liked that it was super girly since Peyton can be a unisex name.
Re: Middle name to go with Drew for a girl
Not that it matters but I think Drew is adorable for a little girl.
I'd use something super girly for a middle name: Lily, Elisabeth, Lilith, Isabella, Ayla, Lola, Leyla, Noelle...
I agree about using something feminine.
