I think it's pretty much the most adorable name ever! I'd consider using it, but my DH doesn't like it.
I think that's a decent sibset.
Elizabeth is a bit odd in it, but with the nn
Bess it fits better.
I haven't worked on
Edith combos in forever, but my combo is
Edith Isobel. It's a fairly hard name to pair well, I've found.
