Welsh names - how popular is Taliesin?

[TierAufTier]

We are not in Wales but have Welsh heritage and so are thinking of names for a DS. Taliesin is the favourite so far.
If you are in Wales do you know any Taliesins? Is it a fairly popular name there or is it still quite 'out there'?
Thank you! :)

I wanted it for ds, Welsh dh was having none of it! I had Taliesin and Idris on my list.

I live in very Welsh area of North Wales and haven't met any.

I know a Welsh cob called Taliesin, not sure if that helps
