Rhodri & elder daughter of Reginald King of Man [Ref: Paul Reed SGM 10/20/1999]
Research Notes:
1170: defeated his brother Hywell at the battle of Pentraeth [Ref: Paul Reed SGM 10/20/1999]

1175: imprisoned by Dafydd, but escapes from captivity and drives Dafydd out of Gwynedd west of the Conwy, establishing a balance of power [Ref: Paul Reed SGM 10/20/1999]

1175: enters into an alliance with Rhys ap Gruffydd, Prince of South Wales, and marries one of his daughters [Ref: Paul Reed SGM 10/20/1999]

abt 1192: betrothed to the Pincess of Man, and married her abt 1193 [Ref: Paul Reed SGM 10/20/1999]

1193: subjugated the isle of Mona (Anglesey). It was apparently called "the Gaelic summer" because of the influx of Gaelic-speaking men from the Isle of Man that had accompanied Rhodri into Gwynedd [Ref: Paul Reed SGM 10/20/1999]

1194: "And king Richard returned from Jerusalem. And then Llywelyn, son of Iorwerth, and Rhodri, son of Owain, and the two sons of Cynan, son of Owain, combined against David, son of Owain Gwynedd, and oppugned all the territory of David, except three castles." [Brut, 240-1.]

But conflicting accounts indicate that Rhodri sided with David and was defeated by Llywelyn at Coed Aneu in Anglesey, and that Rhodri's defeat left him with almost nothing. DWB says it is unknown if Rhodri "returned from exile and shared in his brother Dafydd's humiliation in 1194". Lloyd makes reference to the various conflicting sources [2:588-8]. [Ref: Paul Reed SGM 10/20/1999]

From the third letter of Pope Innocent III, concerning the negotiations for marriage between Llywelyn and the daughter of the King of Man:
Rhodri was betrothed to the girl before she was of nubile age.
Witnesses testified that the girl was betrothed, aged 8, to Llywelyn with her consent as well as that of her relatives; but because of subsequent necessity (political?) he declined to take her to wife, and the uncle was betrothed to her without her consent. The uncle died before having carnal knowledge of her. (That the uncle died without knowing her appears to be false testimony, the motive for which was an attempt to avoid any impediment that woul dhave prevented her from being able to marry Llywelyn) [Ref: Paul Reed SGM 10/20/1999]
