I have checked with all these names in Arcane Legends, they are not in use as of the time this is posted.
Most of them are created by myself, I don't know whether you will like them but I hope you will.
By the way, some of them are more suited for a specific gender.

Besiel
Uleyssis
Briken
Kravien
Kingsery
Lothrium
Titus
Dilchien
Wikton
Neofrugins
Khiamhee
Messilondus
Layamen

Grekanberd
Kiranate
Dorgoi
Itzlebrian
Nyonberd
Rakenbell
Hugofironus
Geopyro
Valdenhowl
Yufrus
Hinxton

That's all I can think of for now, hope you like them!
