I guess. I don't think -ith is a heavy sound though, but I suppose some do. That's their problem with Agatha too, but I don't think that sounds harsh either.Anyway, EdithWren is quite sweet. I can see her being very nit-picky with her various backyard gardens.
To me it's more the Ed- part that feels heavy, with slight overtones of Edward. Personally I dig the heaviness of it. It's just not the majority opinion, sadly. I wonder how Enid would do if she got the chance. . . . Agatha -- love!
