1503, holding along with the latter the prebend of Bromesbury in the same church. He built a house near St. Paul's for his successors in the treasurership, and distributed five hundred marks to the poor in London in time of dearth (Leland, Collectanea, 2nd ed. ii. 324). He was made archdeacon of Lewes in 1509, and on 22 July in the same year, vacating his London appointments, he was consecrated bishop of St. David's, to which he was promoted by the pope's bull of provision dated 13 Jan. 1508-9.
To Vaughan has been assigned 'the most prominent place among the prelates who occupied the see of St. David's during the closing days of the ante-reformation era' (Jones and Freeman). Excepting Gower, the see never had a more munificent benefactor. In lieu of what had been, up to his time, a 'vilissimus sive sordidissimus locus,' he erected at St. David's 'the beautiful chapel' which still bears his name. On its walls he placed three coats-of-arms, namely, his own, those of Henry VII, and of Sir Rhys ap Thomas, 'who probably had been once his patron' (Willis, pp. 77, 89), and who spent his latter days at Carew Castle, close to Lamphey, which was then an episcopal residence (Laws, Little England, p. 235). He remodelled and roofed the lady-chapel and its ante-chapel, while the roof of the nave, and probably also the porch and the upper stage of the tower, belong to his period. He also built the chapel at Lamphey, and Leland (loc. cit.) ascribes to him the chapel of St. Justinian (now in ruins), the chapel at Llawhaden Castle, where Vaughan often resided, together with general repairs at the same place, and a great barn (now destroyed) at Lamphey. 'The beautiful interior decoration' of Hodgeston church is supposed to be his (Laws, p. 232).
Vaughan died in November 1522, and was buried in the chapel which he built and which bears his name. Over him was placed 'a plain marble tomb, with his effigy in brass richly engraven,' and underneath an inscription, which is quoted by Browne Willis (p. 20). All that now remains of it is 'a large slab of shell marble, immediately in front of the altar.' His will, dated 20 May 1521, was proved on 27 Jan. 1522-3.

VAUGHAN or VYCHAN, Sir GRIFFITH (d. 1447), soldier, was son of Griffith ap Ieuan and his wife Maud. The father was implicated in Glendower's rebellion in 1403 and defended Caus Castle for some time against Henry IV's forces; his deeds of valour were celebrated in a poem by Lewys Glyn Cothi (Gwaith, 1837, pp. 423–5). The son, who in 1406 was styled Sir Griffith (Vaughan or Vychan, meaning simply ‘the younger’), was apparently not involved in the rebellion; he figured on the roll of burgesses in Welshpool in that year, and inherited lands in Burgedin, Treflydau, Garth, Maesmawr, and elsewhere. He accompanied Henry V to France, and fought at Agincourt on 25 Oct. 1415, when he was made a knight-banneret (College of Arms MSS., Prothero, vii. 186, 195, and E. 6, 99). Towards the end of 1417 Sir Griffith and his brother, Ieuan ap Griffith, made themselves notorious by capturing on their ancestral estate at Broniarth Sir John Oldcastle the lollard, upon whose head a price had been set. Various privileges were granted them for this act by a charter from Edward de Charlton, lord of Powys [q. v.], dated 6 July 1419, and still preserved at Garth (‘A Powysian at Agincourt’ in Montgomery Collections, ii. 139). No further notice of Sir Griffith occurs until 1447, when he seems to have given offence to the queen, Margaret of Anjou. He was denounced by proclamation as an open rebel, and five hundred marks were offered for his capture. This was effected by Henry de Grey, lord of Powys, who summoned Sir Griffith to the castle of Pool, and gave what Sir Griffith considered a ‘safe-conduct.’ Immediately on his arrival within the court-yard he was beheaded ‘without judge or jury.’ This event, which took place about April 1447, was the occasion of poetical laments by Lewys Glyn Cothi and David Lloyd of Mathavarn (Gwaith Lewys Glyn Cothi, Oxford, 1837, pp. 418–22; Montgomery Collections, i. 335–6, vi. 92–5). On 20 July 1447 a treasury warrant was issued for the payment of the five hundred marks to Grey (Trevelyan Papers, Camden Soc. pp. 32, 36). The deed has been attributed to jealousy on Grey's part because Sir Griffith was descended from the ancient princes of Powys, and had probably laid claim to some of Grey's lands.
Sir Griffith married Margaret, daughter
