Edith seems as classic as
Elizabeth or
Dorothy to me, but
Enid seems antique.
Edith seems graceful at all ages, to me, while
Enid always sounds like a crone, sort of shrewd and tough - and I find it hard to name a baby daughter names that are all crone. Also I think
Enid sounds like a type of insect or worm. I'm assuming it's pronounced EN-id, but if it's pronounced EEN-id I think it sounds way too much like a type of insect, maybe a larva. Weird.
