Madog ap Maredudd

He is recorded as taking part in the Battle of Lincoln in 1141 in support of the Earl of Chester, along with Owain Gwynedd's brother Cadwaladr ap Gruffydd and a large army of Welshmen.

Though he was defeated at the Battle of Ewloe (Coleshill), he was supported by Madog, who was able to regain many of his Welsh lands.

In 1159 Madog would seem to have been the Welsh prince who accompanied King Henry II in his campaign to Toulouse which ended in failure.

The poet Cynddelw Brydydd Mawr in his elegy on Madog said: Edeyrnion (or Edeirnion) was a commote inherited by Owain Brogyntyn and had been the home of his mother (who was not married to his father).

[4] Madog's intervention in the Battle of Lincoln in 1141 forms an important plot element in the detective novel Dead Man's Ransom, part of the Brother Cadfael chronicles by Edith Pargeter (writing as Ellis Peters).
