William ap Watkin Vaughan, Knt., of Porthami (in Talgarth), Breconshire, Wales, Sheriff of Breconshire, 1540-1, knighted 1542.

He obtained a lease of the demesne lands of Dinas on 14 Feb 1529. He was the squire of Porthaml when Leland visited the place, and in 1536 he welcomed bishop Rowland Lee so royally that the latter commended him in his correspondence with his master, Thomas Cromwell. Vaughan, said the bishop in 1538, was a man to be cherished. On 17 Dec. of that year he was appointed chancellor and receiver of the lordships and manors of Brecon, Hay, Cantrecelly, Penkelli, and Alexanderston, offices which he held till 7 July 1546, when he vacated them in favour of his son Roger. In Oct. 1546 he was given wardship of Joan and Elizabeth, sisters and co-heirs of Henry Myle of Court (Joan married his second son Walter Vaughan of Moccas, and Elizabeth his grandson, Rowland Vaughan). He died between 6 Mar 1547 and 5 Dec 1549. ^{1 2}
