The Dauntseys were an old Wiltshire family, which derived its name from the parish in the hundred of Malmesbury. In 1344, John’s grandfather, Sir Richard Dauntsey, settled on him in remainder the manor of Wilsford Dauntsey and two other manors in the county.
Dauntsey’s career had begun by May 1361 when, already a knight, he took out royal letters of protection to serve overseas. Within a few years he entered the service of Edward, Lord Despenser, a knight of great renown, and probably fought with him in his campaigns abroad. It seems likely, however, that he did not travel with his lord to Italy in 1368, for in the following year he was acting at home as a feoffee of two manors in Cambridgeshire which belonged to Despenser’s father-in-law, Bartholomew, Lord Burghersh. Dauntsey was at sea in Despenser’s retinue from August until October 1372, however, and in the following April he was the first to witness an important charter granted by him at Cardiff castle. In the course of the next two years Lord Edward not only named Dauntsey as a feoffee of his estates in Glamorgan, for the purposes of a settlement on his wife, but also appointed him as an executor of his will. In the latter capacity, Dauntsey was long engaged in putting his lord’s affairs in order after Despenser’s death in November 1375: as late as 20 Jan. 1377 he received from the Exchequer part payment of the £425 owing to the deceased as wages of war for his last military expedition (to Brittany).
Despenser’s heir, Lord Thomas, was a minor and was long to remain so. Accordingly, Dauntsey now attached himself elsewhere: to Richard Fitzalan, earl of Arundel. In 1381 the earl named him as one of his feoffees of the marcher lordships of Chirk and Chirksland, and on 20 Jan. 1386 obtained a royal licence to grant Dauntsey a yearly rent of £20 from his manor of Keevil in Wiltshire, for term of his life. In March 1387 Dauntsey enlisted in the force which put to sea under the earl as admiral, and fought some successful naval engagements against the French and their allies. Whether Arundel had anything to do with Dauntsey’s six elections to Parliament for Wiltshire between 1378 and 1388 may not now be ascertained, but there can be little doubt that he would have welcomed his retainer’s support in the last of these, the Merciless Parliament of February 1388, in which the earl played so prominent a part as one of the Lords Appellant. That the latter had confidence in Dauntsey is clear from his appointment, at the dissolution of the Parliament, to administer in Wiltshire oaths of allegiance to them and their new government.
In his will Dauntsey requested burial at Dauntsey church ‘with the puryest, wythoute any other coste or solempnitee ... and I wille and byde that I be layde in the erthe naked as I cam into the yerthe’. Such a provision for a simple funeral was common among supporters of the lollard heresy, but there has survived no further evidence to suggest that Dauntsey held unorthodox views. He died on 31 Oct. 1391, and was succeeded by his son, Sir John Dauntsey junior, aged 34.
