Cadwgan ap Bleddyn

However, Rhys returned later the same year with a fleet from Ireland and defeated the men of Powys in a battle in which two of Cadwgan's nephews, Madog and Rhiryd, were killed.

[citation needed] They were able to return to Wales the following year, and Cadwgan was able to reclaim part of Powys and Ceredigion, on condition of doing homage to Earl Robert of Shrewsbury.

In 1103 he was arraigned before a royal tribunal and imprisoned, leaving Cadwgan as sole ruler of the parts of Powys not in Norman hands.

The justiciar of Shropshire, Richard de Beaumais promised members of other branches of the ruling house of Powys extensive lands if they would join in an attack on Cadwgan and Owain.

Ceredigion was invaded and Owain fled to Ireland, while Cadwgan made his peace with the king but was allowed to hold only one border vill.

King Henry I of England later allowed him to have Ceredigion back on condition of paying a fine of £100 and promising to have nothing to do with Owain in future.

The direct descendants included: Hywel Sele, the cousin of Owain Glyndŵr, also Nannau, Nanney families as well as the cadet branches from the 16th century in the areas of Cefndeuddwr, Tywyn, Maesypandy and Llwyn in North Wales.
