Well, my name is
Edie, and I really like it now (though I didn't when I was a child). However, I have really never cared for
Edith. People have always assumed my name was short for
Edith, which it isn't. It's just
Edie. I was named after my great-grandmother. I can tell you
Edie is very uncommon. I disliked it for that reason when I was a child, but now I love it for the same reason.
Edith is actually a very old English name, and I think it would be nice with
Edie as a nn.
