The chapter on Bishopstrow in A History Of The County Of Wiltshire, Volume 8, Warminster, Westbury And Whorwellsdown Hundreds, originally published by Victoria County History, 1965, mentions that:
The modern civil parish [Bishopstrow] differs from the ancient parish by the addition to it in 1884 of Eastleigh Farm house and the fields near it, and of a small piece of land in the village, both formerly detached pieces of Warminster. At the same time lands formerly called Hillwoods, a detached piece of Bishopstrow near Warminster Common, were transferred to Warminster.
