Are champion names inspired by characters in Ultima games?

I've been a fan on classic CRPG gameseries Ultima since I was a kid. Recently when I've started playing them again and watching Let's Plays of them, I've noticed that many character names strike a noticeable resemblance to characters in them. I'm not sure if I'm onto something but here's a few that I've picked up and I just have a feeling that these can't be a consequence.

Brohm = Braum Garam = Garen Leonna = Leona Jaana = Janna Fiona = Fiora Temme = Teemo Alistair = Alistar Camile = Camille Diane = Diana Shyra = Zyra Ariana = Orianna Kylista = Kalista Jorvin = Jarvan Yasuda = Yasuo

Of course I could be totally wrong but these just bother me :D
