Abigail nn
Abby and
Mary nn
Molly are good, but common for those name.
Margaret nn
Molly interests me a little.
Jenny seems like too modern a nickname.
Nell is something that I really, really like for
Eleanor. Maybe
Ellen, but definitely not
Helen.
It's not your fault, but I don't like
Lilly and
Bella at all.
Tibby is cute. I like it on
Tabitha, but I'm having trouble seeing it on
Isabel.
Libby . . . meh. I've never quite liked it.
Betta is a bit too much like "better."
Addie could be nice for
Adeline. Not for
Adriana, though. My sister's name is
Adrianna and we always call her Adri.
Dell is very sweet. I like it best with
Delphina (and maybe a little more with
Delphine).
Etta is nice. I like it with
Henrietta and
Benedetta.
