I can see why
Emina isn't more common, it sounds like 'enema', not anglo-friendly at all if you ask me, sorry!
Mina is pretty, though.
Elina is all right and I prefer it over
Emina. It does give me a -creative/common sounds combined- vibe so I don't like it very much but it's usable.
Mina and
Ella are much nicer but more common. Do you like
Mila? It's similar sounding and also really pretty. I once knew an Indian girl named Mena which I also like.
