I like
Elina.
Elin is a pretty common name here, where
Elina is more unusual. I've only known two in my whole life, one who is now 20 and another one who is 25 or there about.
Emina..Hmm. I don't hate it, but I don't exactly like it either. It reminds me too much of
Amina, which to me, is very connected to Islam which I'm not a part of what so ever so to me it just feels strange to use Amina/Emina.
