Which spelling is best for this boy name?

I'm really liking this Welsh boy name: Bleddyn (BLETH-in). However, the 'dd' is pretty much the same as the 'th' sound in America. I've come up with these different spellings:





Blethin





Blethyn





Blethan





Blethen





Which spelling is the best? Which looks better and is less confusing for you?

Reply:Blethan or Blethen make most sense to me. Blethyn also looks good and makes sense, if you want to keep that -yn in there.
