Pedigree evidence indicates that direct male descendants of Caraticus held extensive lands along all three coasts of Wales in the 3rd and 4th centuries, and we posit that this extended family ruled the whole of Wales except for the eastern-central lands held by the Cornovii tribe...both before the Romans came and after they left some 400 years later. We further think they had lavish personal manors at several places along the coast which the Romans converted into forts, including Segontium and Caerleon.
While the following is merely our own conjecture, we suggest that by the year 250AD the ruling family had divided their lands into four quadrants, each ruled by a different family branch. In the northwest was Cernyw, so named for the "horn" formed by the Llyn peninsula. Its royal residence was at Segontium and its lands extended east to the Conwy and south to the Dyfi. The island of Mon was given over to the Druids but the rest was later to be called Gwynedd is Conwy. Its first king was Eudaf Hen, born c. 230.
Directly to the east was the kingdom of Llydaw, extending from the Conwy to the Dee and bordering Cornovii lands on the south and east. Men from this kingdom were recruited by Emperor Maximianus Herculius for his Gaul campaign in the late 3rd century and rewarded with lands in Brittany which they named after their Welsh birthplace. Its first king was Gereint ap Einudd of c. 235, a brother of Eudaf Hen. 3
