This branch of the Vaughan family was founded by ROGER VAUGHAN, second son of Sir Roger Vaughan of Tretower. He was possibly the Roger Vaughan of Tyle-glas who was pardoned on 9 July 1491, and figures again in Henry VIII's pardon roll (1509) as Roger ap Roger of Tyle-glas, or Roger Vaughan of Talgarth. He was granted the offices of steward and receiver of the lordship of Dinas, 17 January 1509, and was dead before 25 September 1514, when those offices were granted to Sir Griffith ap Rice. His wife was Joan, daughter of Robert Whitney by Constance, daughter of James, lord Audley. The Vaughans of Tregunter descended from his second son, Thomas Vaughan. The heir, WATKIN VAUGHAN, married Joan, daughter of Ieuan Gwilym Vaughan of White Peyton.
The family became prominent with his heir, WILLIAM VAUGHAN, who obtained a lease of the demesne lands of Dinas, 14 February 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 December 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. He was sheriff of Brecknock in 1540-1 and was knighted in 1542. In October 1546 he was given the wardship of Joan and Elizabeth, sisters and co-heirs of Henry Myle of Newcourt. (Joan married his second son, Walter Vaughan of Moccas, and Elizabeth, his grandson, Rowland Vaughan.) He died before 1553, for his wife, Catherine, daughter of Jenkin Havard, was living in widowhood at White Peyton when she received a pardon on 6 May of that year for being accessory to a murder.
The heir was ROGER VAUGHAN, who was knighted in 1549. He was sheriff of Brecknockshire in 1551-2, and was on commissions to survey church plate in Brecknockshire and Herefordshire in 1553. He figures in queen Mary's pardon roll, 1 December 1553, and received the stewardship of the castles and lordships of Huntingdon and Kington, 6 May 1554. On queen Elizabeth's pardon roll, 1559, he is coupled with Porthaml and Newcourt. He was one of the commissioners who examined on behalf of the privy council the tree which displayed the sign of the cross at S. Donats, 5 June 1561. He was Member of Parliament for Brecknockshire, 1553-62, when he was succeeded by his son Rowland Vaughan, and again in 1571. In the meantime he had represented the borough of Brecon, 1562-7. He died before 31 March 1585 when administration of his estate was granted.
He left several children by his wife, Catherine, daughter of Sir George Herbert of Swansea. The eldest, Watkin, died without issue and the estate passed to Catherine, daughter of the second son, ROWLAND VAUGHAN (Member of Parliament for Brecon, 1559-62, and for Brecknockshire, 1562-7; it seems that he died before the next parliamentary election). Catherine married Sir Robert Knollys (Member of Parliament for Brecknockshire, 1588-1603). Their heiress married the head of the Vaughan family, Sir CHARLES VAUGHAN of Dunraven - see Vaughan family of Bredwardine. ROGER VAUGHAN, of Talgarth, was the third son of Sir Roger Vaughan. He married Frances, base daughter of Thomas Somerset, who married, secondly, William Vaughan of Tretower.
Roger Vaughan's son and heir, also ROGER VAUGHAN, married, in 1608, Ann, daughter of Paul Delahaie of Alltyrynys.
