Just last week I made a mental note to myself to suggest
Dorothy more. I think it's ripe for a comback. It's fresh and youthful and has lots of great nns:
Dora, Dorie,
Dot,
Dottie,
Dodie,
Dolly.
Dorothea I should like more. I love to see classics coming back so I smile when I see it. But honestly, it does feel a little strange to me because I'm so used to
Dorothy. It feels that someone unnecessarily put an "-a" on the end of
Dorothy. I know that's silly. I'm sure
Dorothea existed before
Dorothy. It's just a personal quirk of mine. The only
Dorothea I know goes by
Dot /
Dottie. She would be in her 80's by now.
Theodora, on the other hand, doesn't suffer from my quirk, so I love to see it unreservedly. I know a
Theodora who goes by
Dora. She is in her mid-thirties. (We live in the U.S., if that matters to your question.)
Theodora has additional nns that I love:
Thea and
Theda.
Dorothy,
Estella,
Cecily and
Elinor sound like they stepped out of the pages of a Dickens novel. Great sibling set.
