Owain Brogyntyn

[1] He was the son of Madog by the daughter of the Maer du or "black mayor" of Rûg in Edeyrnion however some sources cite his mother as Susanna making him legitimate instead.

In 1160 after the death of his father and his eldest half-brother, he inherited a share of the Kingdom of Powys - specifically, the cantref of Penllyn (which included Edeyrnion and Dinmael).

Owain first married Jonet verch Hywel (whose ancestor was Athelstan Glodrudd of the Fifth Royal Tribe) but with her had no children.

Bleddyn on the death of his father was made Lord of Dinmael, some notable descendants patrilineally of Bleddyn are the Wynn's of Dudleston descended from Howell second son of Owain ap Bleddyn whose coat of arms is the black lion rampart on an Ardent(Silver)shield, who were living in 1634 with the descendant of the family known as Morgan Wynn Barrister at Law living in the parish of Dudleston at the Estate inherited by the family through an earlier marriage, the Pentre Morgan property.

According to Philip York writing in 1799 a cup and a dagger belonging to Owain Brogyntyn were preserved at Rûg in Edeyrnion.
