I think Blade &
Jacenty will be perfect names and fit the way you suppose they'll look just perfectly. And
Kyra will fit beautifuly too!
But I'm a little concerned about
Shay &
Annika. They are both beauriful names but don't seem to fit the darker looks.
Shay is an Irish name and
Annika is a more Scandinavian name, but I do know a little girl named
Annika who has brown hair, her twin sister's name is
Alicia.
Have you ever thought of using
Ariana or
Adriana for one of your daughters? I love those names!
I'm personaly not that fond of
Jacenty, have you thought of
Jason or
Jared or
Jonas? Just a thought.
