APPENDIX,
No. 4. GENEALOGY OF THE BYAM FAMILY. LIEUT.-GEN. WILLIAM BYAM was descended in a direct line, on his father's side, from CARADOC VRAICH VRAS, Earl of Hereford, Lord of Radnor, one of the knights of the celebrated Round Table of King Arthur, (A.D. 540,) who himself sung his praises, emphatically styling him one of the " Pillars of Britain." He was founder of a dynasty of princes not extinguished till after the Norman invasion, when Blethin, the last of the regal order, was slain by Bernard Newmarch, near Brecknock, in 1094, and his territory appropriated to himself, and parcelled out amongst his followers. His son, CAWRDAVE, was equally, if not more celebrated than his father, being also extolled in the Triads, and, like King Arthur himself, chosen (besides the enjoyment of his own territory) to be "Unbennaeth," or supreme monarch of Britain. CAW succeeded his father in his patrimonial inheritance, at this time entitled the Principality of Ferlex and Brecon ; and GLOYW succeeded him ; and HOYW him, flourishing A.D. 640. KYNVARD, regulus of Ferlex and Brecon, succeeded his father, Hoyw ; and KYNDEG, who was contemporary with Cadwallader, and lived A.D. 703, succeeded him.

But the encroachment of the Saxons in his son TEGYD'S time became more formidable than ever, considerably circumscribing his limits, that had originally embraced all the territories lying between the two livers of Wye and Severn ; and TANGWYD, his son, succeeded to very straitened limits, being reduced to the lordship of Radnor, with parts of Montgomery and Brecon ; and ANARAWD, his son, succeeded as regulus of Radnor and Brecon, in the time of Egbert, king of the West Saxons, who united the whole heptarchy into one entire kingdom, henceforward called that of " England." To Anarawd succeeded his son, GWYNGWY, who, though greatly reduced in territory, still affected the regal title, calling himself " Brenhin" Ferlex a Brecheiniog. And to Gwyngwy succeeded his son, HUGAN, called by John de Castares, " Prince of West Wales," but by
