The Stanburghs appear to have originated in Gloucestershire, although their background remains obscure. In the spring of 1447 Sir Maurice Berkeley I* of Uley was to claim that the family were his villeins, pertaining to his manor of Aylburton, but a jury found in favour of Roger and his descendants, and it is possible that Berkeley was simply using the charge as a defence in a dispute over a cloth sale that had turned sour.
Although Stanburgh is not known to have held the mayoralty of Bath, he was clearly of some standing in the community. He served as one of the city constables in 1427-8, in 1432 he was among the four men who certified Bath’s choice of MPs to the sheriff of Somerset and by June 1450 he was ranked among the city’s aldermen.
Few details of Stanburgh’s commercial activities have come to light, but he evidently traded in cloth as far afield as Salisbury and even London.
