Triffyn Farfog

Triffyn Farfog (English: Triffyn the Bearded) was a semi-legendary fifth century king of Dyfed, father of Aergol Lawhir and grandfather of Vortipor. Peter Bartrum estimated his date of birth at around 430 AD.^[1]

Triffyn's name is usually considered as derived from the Roman title tribunus, and in some texts his name is written much closer to the original Latin word.^[2][3][1][4] While Triffyn's parentage of Aergol is consistent in sources, his own descent is now unclear with multiple ancestries claimed in different genealogies.^[5] Early Irish genealogies name Triffyn's father as Aed Brosc [it], an invader of the dynasty of Eochaid Allmuir ("Eochaid the Foreigner"), remembered in his native land as a member of the Déisi.^[6] Welsh genealogies that do not mention Aed Brosc name Triffyn's father as Owain Fraisg.^[7][8] In addition some Welsh genealogies claim Triffyn was a descendant of the Roman usuper Magnus Maximus.^[1][9]

Triffyn is supposed to have married Gwledyr, daughter of Clydwyn ap Ednyfed, though this connection is described in tentative language by Bartrum.^[1]
