I would still like you to put the surname first in the character sheet (so it would be Gruffydd, Iorwerth), but other than that, approved.

I did.  Gruffydd is his given name (and one spelling of the origin of the English name Griffith), and Iorwerth is a common Welsh surname (well, a surname that has origins in the patronymic naming system of pre-modern Wales).
