        Bartrum offers a single pedigree for this man:
        "Meilyr Gryg ap Gruffudd ap Iorwerth ap Owain ap Rhodri ap Gwaeddan ap Brochwel ap Aeddan ap Cyngen ap Eliseg"
        His notes to the pedigree say:
        "Meilyr Gryg, born c. 1170, is said to have lived at Llwyn Melyn near Gregynog, about nine miles west of Montgomery.  He was ancestor of families in Cydewain, including Blayney of Gregynog."
        This is the pedigree of the first Meilyr Gryg, born c. 1025.  The Brochwel ap Aeddan in his ancestry was the first of that name in the Powys Royal family; Gwaeddan was a younger brother of the first Selyf ap Brochwel.  However, the pedigree errs in making Cyngen a son of Eliseg; this Cyngen was a son of Brochwel ap Eliseg.[1]
       Five generations after this 11th century Meilyr Gryg, the family produced another Meilyr born c. 1190 who may, or may not, have been called "Gryg".[2]  The male generations which separated the two men named Meilyr (Llewelyn, Einion, Llewelyn and Llewelyn Fychan) were repeated by the later Meilyr and occur in the pedigree of Evan Blayney of c. 1385. 
        Others have attempted to explain the missing 5 generation gap in the Blayney pedigree[3], but like Bartrum simply ignore a series of marriage matches which confirm a c. 1025 Meilyr Gryg.  By including all these ladies, and accurately dating the men they married, we arrived at this pedigree for Evan Blayney:
                                      685  Eliseg
                                    715  Brochwel
                                     750  Cyngen
                                     785  Aeddan
                                    820  Brochwel
                                   855  Gwaeddan
                                     890  Rhodri
                                     920  Owain
                                    955  Iorwerth
                                    990  Gruffudd
                                 1025  Meilyr Gryg
                                  1060  Llewelyn[4]
                                    1095  Einion[5]
                                   1130  Llewelyn[6]
                              1160  Llewelyn Fychan[7]
                                 1190  Meilyr (Gryg?)
                                   1220  Llewelyn
                                    1250  Einion
                                   1280  Llewelyn
                               1315  Llewelyn Fychan
                                  1355  Gruffudd
                                1385  Evan Blayney
