William Yonge or Young (died c. 1437) was an Irish cleric and judge, who held office as Lord Chancellor of Ireland.
[3] In the same year John Young, presumably a close relative of William, was granted certain lands in County Meath formerly held by him.
[1] Smyth, writing in 1839, had seen his Patent of Appointment as Lord Chancellor dated 19 October 1422 (the original was presumably destroyed in the Public Records Office fire of 1922).
[6] In 1430 the Crown granted him custody of the manor of Portlester in Meath during the minority of the heir, Richard, Duke of York.
Yonge had his own candidate, John Ardagh, one of his chaplains, but the Crown preferred Dyke, who had an exceptionally long and distinguished career as a public servant, culminating in his appointment as Lord Treasurer of Ireland in 1444.
