Rhun ab Owain Gwynedd

Rhun ab Owain Gwynedd was the eldest child of Owain Gwynedd. His mother was an Irish woman Pyfog who was one of his father's many mistresses. Despite being illegitimate he was his father's favourite child and chosen successor. However, his premature death in 1146 is said to have cast his father into a deep depression which was only cured when he heard his forces had captured Mold Castle from the English.
