I chose Dylan as it is a middle aged person's name and a man's name.
Which brings me back to Baby Names. The names that get suggested tend to be ones that were popular in the 1960s.
Friends at school had names like Sian, Bethan, Carys, Rhian, Delyth, Catrin, Iona, Eleri, Eirian, Sioned and Nia. Boys had names like John, Dylan, Dewi, Huw, Rhys, Gareth, Alun, Geraint, Bryn, Iwan, Sion. Some of these names fell out of fashion as they were at the tail end of their popularity.
When someone asks for welsh name suggestions Anwen usually gets suggested but it was a bit old-fashioned when I was at school, the -wen and -wyn names all were. Arianwen gets suggested and they give ARi ANwen as the pronunciation. Eek! It's dated and made up, and mispronounced.
Eira is suggested again and again, probably because of the Eve, Ava, Isla names being so popular. Eira is a pretty name that was not particularly popular over the years, it and Eirlys (Snowdrop) tended to be given to girls born in snowy weather. Eira pronounced Ira or Ay-ruh are not pretty. Eirlys said as Air-liss isn't pretty either.
I heard someone on the radio refer to Tell Airy. She was talking to a Teleri. Cringe. I've had people argue with me on here re the pronunciation of Eleri. I know so many Eleris! I've also seen someone say Osian is welsh for Ocean and pronounced the same 
I could go on.
