Llewelyn

I literally thought this was pronounced "Lou Ellen" for the longest time.

This name is really weird and demented. Muhaha.

I think the name itself is very cool, but I'm a bit confused as to how it's pronounced. I've read that the double l in Welsh can be approximated by saying 'h' and 'l' at the same time, but I'm not sure how the rest is said. I like it, but I'm sure that in any place other than Wales (or with anyone who is not familiar with the Welsh language) the pronunciation would be completely butchered.
