Notes for Iago ab Idwal, Prince of Gwynedd:Generation 6
32. Iago ab Idwal, d. 1039 [AC, AU, CS], king of Gwynedd, 1023-1039. [AC.c: "Iacob rex Venedo[d?]i[ae] occiditur."; AU 1039: "Iaco ri Bretan a suis, ... [several others listed] ..., omnes occisi sunt."; CS 1037=1039: "Iaco Ri Bretan a suis occisus est."] [JC.25; see also DNB.10.408]
33. Unknown.[Note:ABT.6i gives her as "Afandreg ferch Wair ap Pyll ..." etc., a supposed descendant of the legendary Llywarch Hen through a string of unidentifiable names.I consider this data doubtful.]
34. Amlaíb mac Sitric (Old Norse Óláfr), royal heir of Dublin, d. 1034 [AU] [GaC] [Note:The names from the dynasty of the Norse kings of Dublin and York will be given here in their Irish forms, which is how they appear in most of the contemporary or near contemporary sources which mention them.Corresponding Old Norse forms will be given in parentheses (based on twelfth and thirteenth century Icelandic sources).]
35. Máelcorcre ingen Dúnlaing [GaC] [See note under #17]
36. Edwin of Tegeingl[Note:PP.36 gives several contradictory accounts of Edwin's parentage, all from late manuscripts, so his parentage should be regarded as unknown.The attempt of David H. Kelley (in "Edwin of Tegeingl", The American Genealogist 46 (1970), 75- 80) to identify him with Edwin of Mercia is unconvincing.]
37. Iwerydd ferch Cynfyn [ByT, p. 101]
38-39. Unknown.
40. Caradog.[Note:As father of Trahaern ap Caradog, his first name is certain from his son's patronymic.As far as I have been able to determine, none of Caradog's alleged ancestors (e.g., in ABT.2a,13,14) is a verifiably historical individual.]
41. Unknown.[Note:The Welsh annals (AC and ByT) refer to Trahaern ap Caradog as a cousin of Bleddyn ap Cynfyn (#24), which has led to speculation that Trahaern's mother was perhaps a sister of Cynfyn ap Gwerystan (#48).However, although we can be reasonably certain that Trahaern and Bleddyn were cousins, this information is not enough to nail down the precise relationship.]
42-47. Unknown
48. Cynfyn ap Gwerystan [ByT, pp. 55, 87, 101; MG.3; JC.27] (also #74)
49. Angharad ferch Maredudd [BYT, pp. 55, 87; JC.27; ABT.1e,7k]
50. Cillin y Blaidd Rhudd [ABT.1d,8b, of which 8b calls him "ap y Blaidd Rrudd", the "ap" being an apparent mistake.]
51-63. Unknown
