Alvina

I know someone who has Alvina as a middle name, it is pronounced Al-vi-na, with a long i.
I prefer this to Al-vee-na.

This is my grandmother's name, and she/we have always pronounced it Al-vye-na, with a long I. I love it, so cute and quaint!

The name's Americanized pronunciation is often "Al-veye-na" with a long "i".
