How do you pronounce Volodymyr and Ymar?
Most of these names don't seem usable, especially not Hunger, Senator, Posessor, or Hunger.
I like Caspar, Casimir, and Helier.
Volodymyr is a Ukrainian saint and it's roughly pronounced as 'voh-loh-DEE-meer" (I don't speak Ukrainian so that's the best I can do). It's closely related to the Russian name of Vladimir as well as the Germanic Waldemar.
Ymar was an Anglo-Saxon saint who was martyred by invading Danes. I would pronounce it "ee-mar" because it looks like Mary with the "y" in front.
