#33 - SELYF of DYFED:

          Bartrum actually presents two pedigrees for a descendant of Selyf named Meurig Goch:
(1)  Meurig Goch ap Gruffudd ap Cadifor ap Selyf brenin Dyfed ap Irfelyn arglwydd Hwlffordd ap Tegwas o Abergwavn arglwydd Cemais ap Gwyn ap Aelan ap Alser ap Tudwal ap Rhodri Mawr.
(2)  Meurig Goch ap Gruffudd ap Rhys ap Ifor ap Tegwas felyn arglwydd Hwlffordd
      In his notes, Bartrum says pedigrere (1) is "the commonest and most probable version, but the extension back to Tudwal ap Rhodri Mawr is probably a fabrication, although chronologically possible".  This opinion appears to rely on the fact that Meurig Goch was Lord of Caeo, a commote in Ystrad Tywy far from Dyfed, and the additional fact that Tudwal was known to have owned land in Rhufoniog, even farther from Dyfed.   Bartrum offered no comment at all on his pedigree (2)
      Some 11 years later, Bartrum charted Selyf in his WG as: Selyf (1070) ap Irfelyn (1030) ap Tegwas (1000) ap Gwyn (970) ap Aelan (900) ap Alser (870) ap Tudwal Gloff (830) ap Rhodri Mawr (830)
         Except for the form in which his father's name is presented, we agree with this version of Selyf's pedigree. We find several families descended from Tudwal Gloff who resided, at least for a while, on lands in Dyfed they had inherited from Tudwal. [1]  Selyf married a lady heiress of Ystrad Tywy and we believe he relocated there before the year 1100. [2]
         While this version wrongly inserts "ap Rhys" where "ap Cadifor ap Selyf" should appear, we think it explains why the spelling "Irfelyn" for his father's name is corrupt.  We suggest the phrase "ap Tegwas" is misplaced in this citation and belongs at the end.  Correct alignment would read "Meurig Goch ap Gruffudd ap Cadifor ap Selyf ap Ifor Felyn arglwydd Hwlffordd ap Tegwas"  [3]
         We date the birth of Selyf at c. 1055 which is compatible with Bartrum's Generation 2 estimate.We also found a second family containing a string of same-named men headed by "Cadifor ap Selyf ap Cadfor ap Selyf".  For our full analysis of Selyf's pedigree, see our paper about him at the link below:
[1]  Those families include the ancestors of Gwilym ap Gwrwared, Einion ap Celynin, Llowdden Hen and Cadifor ap Dyfnwal
[2]  Dwnn ii, 50 says Selyf married Efa ferch Morda Frych of Cil-y-cwm in the commote of Mallaen in the far northeast part of cantref Mawr in Ystrad Tywy
[3] Other pedigrees are consistent in saying that it was the son of Tegwas who was Lord of Hwlffordd, and that Tegwas was Lord of Cemais.  See pedigree (1) above.
