Nameberries…which girl name goes best with twin brother “[name_m]Fox[/name_m]”. And why?
[name_m]Fox[/name_m] & [name_f]Lena[/name_f]
[name_m]Fox[/name_m] & [name_f]Nina[/name_f]
[name_m]Fox[/name_m] & [name_f]Maren[/name_f]
[name_m]Fox[/name_m] & [name_f]Gwen[/name_f]
[name_m]Fox[/name_m] & [name_f]Gwyneth[/name_f]
[name_m]Fox[/name_m] & [name_f]Talia[/name_f]
[name_m]Fox[/name_m] & [name_f]Leona[/name_f]
[name_m]Fox[/name_m] & [name_f]Phoebe[/name_f]
I think I like [name_m]Fox[/name_m] and [name_f]Phoebe[/name_f] best–they just seem stylistically best matched to me, for some reason. I [name_u]LOVE[/name_u] [name_f]Lena[/name_f], [name_f]Maren[/name_f], [name_f]Gwen[/name_f], [name_f]Talia[/name_f], and [name_f]Leona[/name_f], though, and almost voted for all of those, too! [name_f]Lena[/name_f] would be my personal favorite name in general. 
Good luck!
My choices in order:
[name_f]Gwen[/name_f]
[name_f]Maren[/name_f]
[name_f]Lena[/name_f]
[name_f]Gwen[/name_f] and [name_f]Phoebe[/name_f] are my favorites!
I like [name_m]Fox[/name_m] and [name_f]Maren[/name_f] because to me they have the most similar naming-style behind them!
[name_f]Gwen[/name_f] is my favorite, with [name_f]Phoebe[/name_f] in second. Normally I’m not keen on alliterating twin names, but [name_f]Phoebe[/name_f] still works alongside [name_m]Fox[/name_m].
[name_m]Fox[/name_m] and [name_f]Gwen[/name_f] is definitely a top-notch combo, both single syllable names with charm and punch. (And both bring to mind the Welsh countryside)
[name_m]Fox[/name_m] and [name_f]Phoebe[/name_f], because they are both unique and compliment one another. [name_u]Love[/name_u]!
[name_f]Phoebe[/name_f] and [name_f]Gwen[/name_f]
