Wilfred Middlebrook, in The Changing Face Of Warminster, first written in 1960, updated in 1971, noted:
Boreham hamlet is said to have been the home of Robert le Bore in the time of Edward The Second. He was also a lord of Hill Deverill and founded a chantry there. At one time Boreham was called Burton de la Mere.
Many different families have held Boreham since the days of le Bore including the Osbornes, the Giffords and the Slopers – one of the Slopers, it may be remembered, occupied a house in Ash Walk, sometimes known as Sloper’s Walk.
In 1820 the reputed manor or tithing was sold to William Temple, who left the old mansion, which stood near the river, and built a new house on higher ground.
In olden times, Boreham was an isolated hamlet, like most of the villages of both the upper and the lower Wylye Valley, with a long stretch of open fields separating it from Warminster.
