John de Sancto Mauro was born at Beckington, Somerset, in a place called ‘Nwbyry’ on 26 May, 1408.
John was the son of John de Sancto Mauro (St Maur, Seymour), and his wife Margaret Erlegh (Erleigh, Erley). His father died on 16 October 1415, and in the Inquisitions post mortem (IPM) held after his death, John was designated his heir though still a minor.
In his father's IPM held at Exeter on 19 December 1415, the John of this biography was described as aged 6 years and more, and in the IPM held at Ilchester on 30 March 1416 as aged 7 years and more, which would place his birth at about 1409.
He married on or before 23 July 1425, Elizabeth, the daughter of Sir Thomas Brook. This is confirmed by a charter of that date, where Sir Thomas Brook, granted to John and Elizabeth, his wife, and daughter of Thomas Brook, the manor of St Michael Church. This charter was shown to the jurors in the IPM of John, held at Somerset on 8 June 1439.
Four children are mentioned in one of their father's IPMs;
John died on 25 September 1438, and a writ was issued on 8 October 1438 to hold inquisitons post mortem on his estate. These were held at Exeter, Devon on 21 October 1438, and Yeovil, Somerset on 29 October 1438. Another writ was issued on 13 March 1439 for another inquisition at Frome, Someset on 8 June 1439. His son Thomas, aged 11 years and more (or 12 years and more in the second Somerset inquisition) was designated as his heir.
