Evanna, as a feminne form of
Evan? Hmm. With so many established feminine forms of
Evan /
John out there, Evanna seems a stretch. It makes me wonder if it's a typo for
Ivanna.
I read on these boards once about Evaine, a French girl's name, pronounced, "eh-VEN." I don't know it's etymology. But it strikes me as a nice way to honor any Evans in the family. Just a thought.
As for your list, Evanna
Catherine is the prettiest to me. Very nice.
