Most of them are too matchy for me, too similar:
Gabriel and
GavinDamian and
DeanDamian and
DianaEphraim and Ellia
Gavin and
GabrielleJane and
Julian - although I do quite like it, despite that
Serena and
DianaDiana and
FionaSeraphina and
Veronica
I think with twins I'd be extra cautious about names being similar. Nothing that is themed, sounds similar, or looks similar... that includes beginning with the same letter.
What ones are left now?
Joel and
Harrison,
Aaron and
Serena, and
Serena and
Giselle. I think
Joel and
Harrison and
Serena and
Giselle are fine together in terms of style, but
Aaron and
Serena are totally out of left field. Also I thought
Aaron said Apron at first. Dude, Apron is an aweome sounding word for a name.
If I were to rearrange, I would really like to see any mix of
Damian,
Harrison,
Julian,
Aaron, and
Ephraim. Yeah, they'd all sound a bit matchy, but that's what I had to work with! You could pair
Jane,
Diana, or
Veronica with any of those too and that would be excellent. Or with each other. Like
Jane and
Ephraim, sweet. Or
Harrison and
Veronica. Yeah.
