We are expecting our fifth child(First girl!) any day now. Many people have told us our boys all have ‘unisex surname’ type names. Since we are planning more kids in the future we were just wondering if we should continue with this unintentional theme or go a different route for this one and the ones to come.
Many people choose one “style” of names for boys and another for “girls”. There are no “rules” set in stone. It’s what YOU want to do not what other people think. If you limit yourself to surnames, your choices shrink. You have to ask yourself what type of name you like for girls. If you can’t find another unisex surname you love for your first girl, then break the pattern. You’re not going to be arrested. 
If I were you, I would choose something totally different for your first girl. It doesn’t have to be overly frilly but I think it should be clearly feminine (eg. [name_f]Claire[/name_f]/[name_f]Clara[/name_f], [name_f]Nora[/name_f], [name_f]Fiona[/name_f], [name_f]Maeve[/name_f], [name_f]Keira[/name_f], [name_f]Isla[/name_f], [name_f]Laurel[/name_f]). Write down a list of girls names you like and post them here for opinions if you want to.
I would choose something more on the feminine side, just so that she stands out a bit from her brothers. But, that’s just me. Whatever you choose, make sure it’s something you love, you’ve got a very cool naming style!
Well, [name_u]Bentley[/name_u], [name_u]Easton[/name_u] and [name_u]Schuyler[/name_u] sound like surnames but [name_m]Maxwell[/name_m] doesn’t. And I can’t imagine any of those on a girl. I think you can go in any direction you like. I don’t think she would stick out if she was [name_u]Avery[/name_u] or if she was [name_f]Samantha[/name_f]–I can see lots of names fitting fine into your set, and since she’s the first girl I think you have even more freedom.
