My Royal Prince needs a name, any helpers?

Hey, I was hoping for a little help. I’m struggling to get a perfect name for my character for a fantasy. He’s male and immortal, with a very old soul (even though he looks young). He has a young daughter who he cherishes dearly and is kind of like a prince in his kingdom. Like a Prince he’s regal and fair. The name should be kinda old fashioned, maybe foreign, yet magical and a little unusual. If আপনি think of something that matches, please let me know because I’m now growing desperate and need all the help I can get. Thank you!
