How is Uaneen (or Oaneen) spelt in Irish?

I'm guessing it's an English version of "Eoinín".

It is recommended that you always wait for three to agree on a translation.
I speak Connemara Irish, and my input will often reflect that.
I will do an mp3 file on request for short translations.

I'd think Owneen or maybe as Bríd saiid and they use the Irish spelling

I think the most common spelling is actually Uaneen so I'll try editing my question to reflect this.

My understanding is that it is the pet form of Úna as apposed to Eoin.

Uaneen Fitzsimons is the only person I know who has had this name.

I'm wondering how Úna and ín can be combined while still obeying caol le caol agus leathan le leathan.
