I like
Edna a lot. I don't think it needs a nn at all, and I don't like
Eddie on a girl. Far too boyish.
Edna gives off the feeling of an old-fashioned, quiet, hardworking girl and
Eddie a redheaded loud boy... I can't see one as the nn of the other, even though it's technically the "natural" nickname.
And
Dolores... curse J K Rowling for ruining this one for me (and for stealing names I liked... I liked Merope before she used it!) Heh. But I didn't really like
Dolores before Umbridge either. And isn't
Dolly the name of the cloned sheep?
Edna Dolores doesn't sound bad as a combo at all.
