[6] Widhill, land lying north of Blunsdon St Andrew as far as the Roman road and bounded to the west by the River Ray, appears in Domesday Book as two estates at Wildehill with altogether 14 households.

[9] In the late 19th century Widhill became part of Cricklade civil parish, then was transferred to Blunsdon in 1934; its population at the 1931 census had been 21.

A monument to John Potenger (died 1733), in white and grey marble with cherub heads, is signed by Peter Scheemakers.

[12] William Butterfield carried out extensive restoration in 1870, when the chancel was rebuilt and the south-east chapel and north-east vestry were added.

[17] The village has a football team, Blunsdon FC, which has youth development squads as well as senior ladies and men's sides playing in the Wiltshire League.

In the southeast, the boundary with St Andrews leaves the A419 and follows the A4311 Cricklade Road, so that the Groundwell industrial estate is in Blunsdon parish.

[20] Located in the car park of the village hall, the shop was originally based inside a secondhand site office cabin, but in 2009 this was replaced by a brand new structure.

Margaret de Windt (1849–1836), daughter of the builder of Blunsdon Abbey, married the White Rajah Charles Brooke and thus became Ranee of Sarawak.
