In the 8th century, a Brythonic prince named Demorris ap Rhodri was a prominent figure in the Kingdom of Gwynedd, located in present-day Wales. He is mentioned in several medieval Welsh manuscripts and is remembered for his efforts to unite the various Welsh kingdoms against the invading Anglo-Saxons.
During the Norman conquest of England in the 11th century, a Norman knight named Demorris de Beaumont fought alongside William the Conqueror at the Battle of Hastings in 1066. He was later granted lands in Warwickshire and became a prominent figure in the Norman aristocracy.
