I like to see Iona, Rhys, and Meira. Rhodri is interesting. CaiElis is my favorite combo here. Can you, or anyone else, tell me more about Osian and Einir?
Osian is the Welsh version of Oisin / Ossian. It's pronounced OSS yan. It's one of the most popular Welsh boys' names in current use, although it's not really used outside Wales. I don't have a reliable meaning for Einir (AY neer, ay as in may) which only seems to have been in use since the 1920s.
