Blethin and Riwalhon the Sons of Convyn.
After the decease of King or Prince Gruffith, Meredith the son of Owen ap Edwin (which Edwin was son, as some Writers say, to Howel Dha) did take upon him the government of Southwales; and Blethin and Riwalbon the sons of Convyn and half Brothers to King Gruffith ap Lhewelyn (as they which were born of Angharat, daughter to Meredith King of Wales) did govern Northwales; Conan the son of Jago being all this time with his Father in law in Ireland.
Caradock ap Gruffith ap Rytheryc, was the first that procured Haroald to come into Wales against Gruffith ap Lhewelyn, hoping by him to attain unto the Government of South∣wales; but it fell ontotherwise; for when Haroald understood that he should not get that which he looked for at the hands of Caradock, which was a certain Lordship within Wales nigh unto Hereford, and knowing also Caradoc to be a subtile and deceitfull man, compoun∣ding with Meredith ap Owen for that Lordship, he made him King or Prince of Southwales, and banished Caradoc out of the Countrey. Afterward Haroald having obtained that Lordship, builded there a stately and princely house, at a place called Portashlyth, and di∣vers times earnestly invited the King to come and see the same, and at length the King be∣ing then at Glocester not far of, granted him his request, whereupon Haroald made such preparation as was most wonderfull, and as much abused: Soon after this, the said Caradoc ap Gruffith came to the same house, and to be revenged upon Haroald, killed all the work∣men and labourers that vvere at vvork, and all the servants and people of Haroald that he could finde, and defacing the vvork, carried avvay those things that with great labour and expences had been brought thither, and set out and beautified the building.
