Evidence
A 1199 grant to Aberconwy Abbey refers to the grove of Iarddur ap Cyndellw in Creuddyn (Pryce no. 218).
Peniarth 131 (p. 93), a manuscript by Gutun Owain written about 1475, and Peniarth 127 (p. 152), a manuscript written about 1510, give the name string as: Iarddur ap Kynddelw ap Trahaiarn ap Bod ap Kysgen ap Helic ap Glannoc. (Bartrum, “Pedigrees of the Patriarchs” 10). There is some variation in later manuscripts which Bartrum considers less reliable.
Peniarth 134 (p. 132), a manuscript by Gruffudd Hiraethog written between 1550 and 1562, has: Iarddur ap Kynddel ap Trahayarn ap Bod ap Kysgen ap Helic ap Glynnoc ap Gwgon gleddyfrydd ap Kariadoc freichfras ap Llyr merini ap Einion yrth ap Kvnedda wledic. Yr Iarddvr hwnn a briodes Elen verch Gynihwr brenin o Ewerddon, a thair merched a wnaeth i Gyniher yma ar vnwaith. Yn att Gruffudd ap Llywelyn ap Iowerth, Katrin oedd i henw. Y 3dd verch Gynihwr, Katrin vechan gwraic Maredudd ddv ap Grono ap Maredudd ap Iorwerth ap Llowarch ap Bran. Ar Iarddur hwnn oedd debiti yn Ywerddon yn amser Llywelyn ap Iorwerth a chwedi ef yn amser Ed. Kwngkwerwr. (Bartrum “Pedigrees of the Patriarch” 10).
Peniarth 138 (p. 326), a manuscript by Gruffudd Hiraethog written about 1562, Peniarth 140 (p. 19), a manuscript by Wiliam Llŷn mostly written before 1569, and Peniarth 74 (p. 33), a manuscript by Simwnt Fychan written in the second half of the 16th century, have: Gwervyl goch verch Gynan ap Owain Gwynedd, gwraic Iarddvr ap Trahayarn ap Kynddelw ap Ririt ap Bod ap Kysgen, hon a wnaeth Bettws Gwerful goch, ai chaddv yNinmael. (Bartrum “Pedigrees of the Patriarch” 10).
