Help with middle name!

As of now Charlotte is a clear winner for our baby girls name. We’d like to call her Charli for short but can’t seem to agree on a middle name. I want a family name from my side since she is going to get my husbands last name (&mine now too)

Some family names I love are:

Elizabeth- ( this is my sisters name and she named her daughter Evelyn Cameron after me )

Parker

James - (husband says charli james sounds too boyish)

Montgomery

I’m also open to non family names but would love suggestions!
