Hugh Waterton

By 1375 he had acquired the manor of Eaton Tregoz near Ross-on-Wye in Herefordshire, which by an inquisition taken after his death was found to contain castle buildings and a deer park of 144 acres.

[9] When Bolingbroke came to the throne as Henry IV in 1399, Waterton was appointed Chamberlain of the Duchy of Lancaster, a position which he held until his death.

Numerous other offices and grants followed, including his appointment, in 1401, as steward and constable of four Lancastrian castles in Wales at Monmouth, Grosmont, Whitecastle, and Skenfrith.

[2] On 1 October 1401 he was appointed one of the 'Custodes' of Henry IV's underage son, Thomas of Lancaster, who was travelling to Ireland to serve as Lord Lieutenant.

[9] During Henry IV's reign Waterton continued to be appointed to commissions in Gloucestershire and Herefordshire, including Justice of the Peace.

[2] In May 1402 he was one of the commissioners authorised to negotiate the marriage of the future Henry V of England, then Prince of Wales, with Catherine, adopted daughter of Margaret I of Denmark.
