#4 - CADWGAN FANTACH
 
       Although Bartrum had not yet discovered, when he wrote his "Patriarchs" paper in 1963, that there were two men named Cadwgan Fantach who share a common ancestor, he did present two separate pedigrees:
 
        (1) "Kadwgon vantach ap Kadwgon ap Llywelyn ap Gruffudd ap Ridid ap Edelvrych ap Peredur peiswerdd arglwydd Keredigion uchaf"
 
        (2) "Kadwgon vantach o Lannddewi vrevi ap Gruffudd ap Maredudd ap Einion ap Rhys ap Karedic ap Klodrydd ap Gwallter ap Pill ap Predyr peisswyn ior Karedigion"
 
         In his notes, Bartrum said:
 
         "Cadwgan Fantach of Llanddewi Brefi, born c. 1200.  The male line ended with his son Maredudd, who left three heiresses.  See Dwnn i, 82, 94, 222, etc.  [Pedigree (2)] seems to show confusion with [the pedigree for Rhys Chwith]"
 
          When Bartrum published his Welsh Genealogies AD 300-1400 in 1974, he charted separate men for his two pedigrees, both descended from a consolidated Peredur Beiswrydd/Beisgwyn but from different sons of Peredur.  There, he dated the Cadwgan Fantach who had the son Maredudd to c. 1200, while he makes Cadwgan Fantach II born c. 1300 and the man who lived in Llanddewi Brefi in the commote of Pennardd.
 
          We would date the earlier Cadwgan Fantach (the toothless) to c. 1205 based on our analysis of the marriage matches cited for his son and granddaughters.  His son Maredudd married Gwenllian[1] ferch Maredudd ap Owain ap Gruffudd ap Lord Rhys, a lady born c. 1240.  The daughters of Maredudd married men[2] born form c. 1250 to c. 1260, so these ladies should be dated c. 1265/70.  The pedigree (Bartrum's #1) which he proposes for this Cadwgan Fantach is a generation too short (he dates Peredur 25 years earlier than our estimate).  Alternate pedigrees[3], which Bartrum mentioned, substitute the name Maredudd for Rhiryd as the grandson of Peredur; we suggest both names belong in the pedigree although it is only a guess which of the two was the father of the other. 
 
         We propose the following chart:
 
                           995  Peredur Beisgwyn
                                          l
                             1025  Edelfrych
                                          l
                              1055  Rhiryd
                                          l
                            1085  Maredudd
                                          l
                            1115  Gruffudd
                                          l
                            1145  Llewelyn
                                          l
                            1175  Cadwgan
                                          l
                          1205  Cadwgan Fantach
                                          l
                            1235  Maredudd
                                          l
                    1265/70  Three daughters
 
           The man whom Bartrum calls Cadwgan Fantach II is the one whose residence is cited as Llanddewi Brefi.  We estimate his birthdate as c. 1310.  He lived near the Tregarron manor of the Clement family whose men were in the military service of the English Crown, and he married a daughter of the Lord of Pennardd, Sir Robert Clement[4], son of the second Geoffrey Clement. While not named in the sources, this lady was born c. 1325. 
 
           The Bartrum pedigree (his #2) is a generation short as given.  Other sources[5] cite a "Ceredig ap Gwallter ap Pyll ap Peredur Beisgwyn", so we would insert Ceredig between "Klodrydd" and "Gwallter" as:
 
                             995  Peredur Beisgwyn
                                           l
                                1025  Pyll
                                           l
                              1055  Gwallter
                                           l
                              1085  Ceredig
                                           l
                              1120  Clodrydd
                                           l
                              1150  Ceredig
                                           l
                                1180  Rhys
                                           l
                               1215  Einion
                                           l
                             1245  Maredudd          Geoffrey Clement II 1265
                                           l                            l
                              1275  Gruffudd           Sir Robert Clement  1293
                                           l                            l
                        1310  Cadwgan Fantach II====daughter  1325
 
         In our analysis of Bartrum's pedigree for the common ancestor of these men, we shall present our reasons for identifying him as Peredur Beisgwyn (not Beiswrydd) and for dating his birth c. 995.
