Ed. I think the masculine nn isn't well liked even for a man, let alone a woman. That's my theory anyway.
I like
Edna well enough. I just prefer
Eithne, (which my mother's dialect pronounces as "ET-nuh,") better. It's similar to a favorite of mine,
Edme. I love the heaviness of
Edme, compared to light-as-air
Esme. So the
Ed part of
Edna doesn't bother me.
We used to have regular on here that would use
Edna for a dd some day, in honor of
Edna St.
Vincent Millay. :-)
If I met a little
Edna it would make my day. I love seeing almost any "old lady" name being reused. Where others see/hear "old lady" I see/hear "old soul."
