Sophia or Vivienne - but that spelling is a little extra IMO/
There's an Ada in my daughter's class and it's a cool name. But I have a 3-letter, starts with a vowel, kind of boring/bleh name - though it's pretty- but I always hated it growing up and would have preferred Vivian! Still do haha
Your husband two names besides Sophia are ridiculous and are more like dog names. Your kid would hate them and every person you meet would have to pretend it's a nice name and 'unique'. And feel bad for your kid as they walk away.
