What could Mimi and Nina be short for?

[kmini]

Trying for dc2 and starting to consider names again. We have a Thomas (always Tom or Tommy) and have always adored Tessa (tess) if we had a girl.

However, two names I have also always loved are Mimi and Nina. Nina, like Tess, is a name in itself but are there any names Nina could be short for? Mimi is more of a nickname imo, so definitely needs to fuller name on the BC.

Any suggestions?

Both can be a nickname for Marina.

If I met a Mimi and a Nina, I would automatically think Miriam and Christina.

Antonina
Miriam
Maria

Mimi is short for Jemima here. Never heard of it as a nickname for anything else.

Nina is a (lovely) stand alone name.

My friend is called Marie, but known as Mimi as her niece called her that when little and it stuck!
