I feel like I should like
Fiachra more than I do. There was a character on kid's TV years ago called
Fiachra Frog and the association always stuck with me. I like Fiach though. I think it would be easy enough to pronounce.
Fiachra AodhanFiachra RonanFiachra Darach
Fiachra Aodh is nice but then I have a soft spot for
Aodh.
