Unfortunately no, all we have is speculation and a very small tidbit of info from Andre.

Apparently blacksmiths who can forge Divine weapons usually come from Thorolund or Astora de to their close relationship to Lordran, though with Lordran being the home of the gods there would almost certainly be Divine Blacksmiths there.
