The sons of Beli Mawr were the ones who had to face all those Latin speaking and writing Romans, who came to take the island from us. Ashley in his book identifies Llud as the eldest son. He is credited with rebuilding a town which he called KareLud after him. It was then called Lud's Town, which the Celtic tongue pronouned "London". Llud died and is supposed to be buried by the city wall where the gate became Ludgate. It was on Ludgate Hill that many generations later the smartest linen drapers and silk mercers had their shops. [Drapers and mercers where active in my Jones family.]
Ashley also describes Caswallon (a brother to Llud), as the earliest known historical British king. The Latin writers would call him Cassivelaunos and identify him a the ruler of the Catuvellauni tribe. [Their land was north of the Thames involing Hertfordshire, Bedforeshire, Oxfordshire, and Berkshire.] Salway in his text even states that coins were minted and buriels would suggest a great deal of power and prosperity of their ruling families.
Afflech is no where to be found except in the genealogy given by Dwnn. He would have been near and involved in the battles which faced these ancient Britons. It is through Afflech that my Jones line derives its Y-chromosome.
Ashely's book discusses the early British kings "Pre-Roman Conquest" pp.66-80. Llud and Caswallon pp.69-70.
