Taliesin is a name like Arthur and Merlin (Myrddin). It has been around for a long time to say the least. I believe the following poem called the Hanes Taliesin tells us the story of the Merovingians back to a time even before Melchizedek.
Hanes Taliesin
1. An impartial Chief Bard Am I to Elphin. My accustomed country Is the land of the Cherubim.
2. Johannes the Diviner I was called by Merddin, At length every King Will call me Taliesin.
