Edna is one of those names that, until what it seemed like a few minutes ago, felt so terminally frumpy that no one could imagine a parent choosing it for an innocent modern baby girl. But with the great upswing in names honoring ancestral family members, several of them being other four-letter, e-ending names, we wouldn't be so sure.
Edna, which means delight, is a semi-biblical name--in the Apocrypha she is seen as a loving mother-- and was enormously popular in this country in the late nineteenth century, reaching as high as Number 11. It also relates to Eden--another, more contemporary sounding, option.
Three literary bearers of the name are Edna St. Vincent Millay, Edna Ferber and Edna O'Brien, and to some the name might be identified with the campy character, Dame Edna Everage.
