ERPINGHAM, Sir THOMAS (1357–1428), soldier, born in 1357, was son of Sir John Erpingham, who died on 1 Aug. 1370, and was buried in Erpingham church, Norfolk. The family claimed to have been settled at Erpingham from the time of the Conqueror (Blomefield, Norfolk, vi. 412-413), but the earliest to be lord of the manor of Erpingham was Robert, who lived in the middle of the thirteenth century. A later Robert de Erpingham, probably grandfather of Sir Thomas, represented Norfolk in the parliaments of 1333-4, 1335, and 1341 (Official Return, i. 103, 107, 134). Sir John had, like his son, a house in Norwich, where he mainly resided.
Thomas, who was only thirteen years old at his father's death, was early trained in the profession of arms. In 1380 he was in the service of John of Gaunt, and by an indenture dated at York on 13 Sept. of that year he stipulated for 20l. a year in time of peace and fifty marks in war for himself and a servant, together with the 'usual wages of the bachelors of his sort.' On 8 March 1381-2 he was appointed one of the commissioners to suppress rebellions in Norfolk, and on 21 Dec. following his name occurs in a similar commission for Middlesex. In January 1384-5 he was made commissioner of array in Norfolk in view of the anticipated French invasion, and he constantly served on commissions of the peace in the same county (Cal. Pat. Rolls, 1381-5, passim). In March 1386 he obtained letters of protection on setting out with John of Gaunt for Spain, and sailed from Plymouth on 7 July. In 1390 Erpingham accompanied John of Gaunt's son Henry, earl of Derby (afterwards Henry IV), on his expedition to Lithuania, sailing from Boston on 20 July; and in July 1392, when Henry started on his second journey to Lithuania, Erpingham again went with him. On 23 Sept. Henry sent home most of his followers from Danzig, but Erpingham remained with him, and accompanied him on his adventurous passage across Europe into Palestine. He received various payments from the duchy of Lancaster for his services, and was also granted lands near King's Lynn, Norfolk.
When Henry was banished in 1398 Erpingham was once more his companion in his travels abroad; he was with him at Paris in 1399 and witnesssed the agreement for mutual support and defence which Henry drew up with Louis, duke of Orleans, on 17 June (Douët d'Arcq, Pièces inedites sur le règne de Charles VI, i. 157-60). He landed with Henry at Ravenspur in July 1399, and on 30 Sept. he was appointed constable of Dover Castle. By the parliament that met on that day Erpingham was nominated one of the commissioners for receiving Richard II's resignation of the crown (Rot. Parl. iii. 416, 422). On 5 Nov. he was made warden of the cinque ports, and soon after he was granted custody of the lands of Thomas, duke of Norfolk. In the following January he attended convocation to promise the king's help, and advocate some decided action, in putting down the Lollards (Ramsay, Lancaster and York, i. 32). His selection for this task was singular, as he was himself inclined to lollardy, and was a friend of Sir John Oldcastle (Wylie, iii. 295). In the same month Erpingham was associated with John Beaufort, first earl of Somerset [q. v. Suppl.], in the command against the degraded lords who had revolted against Henry IV; and at the end of the month he was one of the commissioners appointed to try the rebels. Before the end of 1400 he was elected K.G., and was made chamberlain of the king's household.
In November 1401 Erpingham was selected to accompany Henry's second son, Thomas, as one of his 'wardens,' to Ireland, landing at Dublin on 13 Nov. [see Thomas, Duke of
