Overview
Hywel ap Rhys ('Hywel son of Rhys') (ruled 886) was a king of Glywysing (either in part or in its entirety) in South Wales.
His sons Arthfael and Owain were probably responsible for the reünification of the realm of Morgannwg. A third son may have fallen helping Rhodri the Great resist a Mercian invasion of Anglesey around 843.
The Houelt Cross
A cross in the collection of ancient stones at St Illtyd's Church, Llantwit Major has been identified with Hywel. The Houelt Cross has a Latin inscription written in half-uncial Latin which has consistently been interpreted as a memorial cross raised by Hywel for his father.
