The chapter on Upton Scudamore in A History Of The County Of Wiltshire, Volume 8, Warminster, Westbury And Whorwellsdown Hundreds, originally published by Victoria County History, 1965, mentions Thoulstone:
Thoulstone had 22 poll-tax payers in 1377. In 1428 it had fewer than ten households, and in the later 16th century there were about seven houses there. By 1807 there were only three farms; one, the Breach Farm, which lay south of the sharp bend in the road, has since disappeared. Of the other two, that south of the road is a large brick building of the late 18th century, while the one on the other side displays the Gothic taste of a few years later.
