This is going to date me but I think of the young
Princess Diana and how she was known as one of the "
Sloane Rangers", a name based on some area of
London where young well-to-do adults live in apartments paid for by their aristocratic families. So for me
Sloane is kind of a "poor little rich girl" sort of name, which gives it some personality at least!
If I had to choose, I think I'd go with
Sloane, that e on the end makes it slightly more human.
