Mor, King of Mid-South Wales
(Born c.AD 378)
(Latin: Marius; English: Marius)

Mor appears to have inherited his father Owain's estates in Mid South Wales in the late 4th century. Nothing is known of him but, if he existed, he would have been an important landowner and Roman Official rather than a 'King' as such. His position was inherited by his son, Solor.

Mor appears in an 11th century king list. He is generally considered apocryphal.
