Not a fan, but it looks much better than Aidan on a girl. I hope people realize that this is a separate Irish name from Aidan and don't think it's a variant of Aidan.
Aideen O'Kelly (1936 – 2015) was an Irish actress of stage and television, who worked in both Ireland and the United States. She was nominated for a Drama Desk Award for her performance in Othello in 1982.
Wouldn't this be an anglicization of Éadaoin, the more modern Irish form?Because Étaín is AY-teen, not AY-deen. And Éadaoin is EH-deen (but in an English pronunciation would sound more like AY-deen). [noted -ed]
For anyone that makes assumptions, Aideen has ZERO connection with Aiden and Aidan. They mean completely different things and come from different roots, so Aideen is not exactly a feminine form of Aiden.
My middle name is Aideen, and I have yet to meet anyone who has ever heard of it, let alone has it as a name. My parents say they chose it becuase my god-father's sister was Nadine, and thought Aideen would be different and unusal. They were right. No one has ever been able to guess my middle name.
