Katalin for a girl - Kat-ah-lyn

I know a lot of people in this group downvote anything that is somewhat unique, lol, but.. my daughter is half Spanish and I want to give her something that is unique yet not made up.

I love the nickname Kat.. so we would call her that most of the time. But Katalin? What do you think? even maybe Katalina, another option.

And I will reiterate - no, it is not a made up name!! Lol 😆
