OK of all the names you mentioned, I'll note which ones I hear a ton of around here:
Emma - very popular
Abbie - very popular (and many similar names like Allie, Addie, etc.)
Ava - very popular
Isabelle - very popular
Elise - not as popular, you could call her Ellie

Amy - not popular with the younger ones, just people my age it seems (late 20s)
Amelia - pretty popular here as well
Lillian - not as popular but Lily is for sure
Josephine - Believe it or not, pretty popular here, I know 2, both go by Josie
Vivian - not popular here
Honestly, even though you don't want a popular name, it seems like you are really more attracted to those since the ones you like seem to be way up on the charts, so just go for it if that is what you like.
You can see which ones are most popular in the US and how they rank here ....
