To Madog is assigned the honour of erecting the Castle of Oswestry. Whether he is entitled to this distinction it would be difficult now to prove. Welsh historians assert, that he built also the Castles of Overton (Flintshire) and Caereinion, and that in the former, which received the additional name of Madog, he resided. Powell says of him, that he was “ever the King of England’s friend, and was one that feared GOD, and relieved the poor.” Madog married Susanna, daughter of Grufydd ab Cynan, Prince of North Wales, by whom he had two sons, Grufydd Maelor and Owain ab Madog. To the first he gave the two Maelors, Yale, Hopedale, Nanheudwy, Mochnant-is-Rhaiadr, &c.: to Owain, the land of Mechain-is-Coed; and to his natural son, Owain Brogyntyn, a nobleman of distinguished talents, he granted the lordships of Edeirnion and Dinmael. The last-named Owain resided at Brogyntyn, near Oswestry, now called Porkington, whence he assumed his surname. His dagger and cup are still preserved at Rûg: and many families in Merionethshire and Denbighshire are directly descended from him. Madog’s second wife was Maud Verdon, an Englishwoman of noble lineage. He died in 1159 at Winchester, whence his body was conveyed to Meivod, in Montgomeryshire, where it was deposited in the Church of St. Mary, which he himself had built some years before. His widow is stated to have been married to William Fitz-Alan, Lord of Clun, and he, in right of his wife, obtained the town and castle of Oswestry. Fitz-Alan was a descendant of Alan, one of the companions of the Conqueror, and was the first of his name who bore the title of “Baron of Oswaldestre.” Alan was progenitor of the entire noble family which from him derived the name of Fitz-Alan, and for many succeeding centuries were the most distinguished personages in Shropshire. From this powerful race is descended the present Duke of Norfolk, who holds the title of “Baron of Oswaldestre,” in addition to his other patrician honours. His Grace’s ancestor, Thomas, Duke of Norfolk, married Lady Mary, daughter of Henry, the last Earl of Arundel named Fitz-Alan, 13th Elizabeth, when the barony of “Oswaldestre” was conveyed to the Duke.
