In 1086 Hathern was part of the manor of Kegworth, which was held by Robert from Hugh, Earl of Chester. Hathern and Dishley accounted for 3 carucates of ploughland. The manor belonged to Robert le Bossu, Earl of Leicester at his death in 1168, passing to his son Robert Blanchmains and then to his grandson Robert Parnell, who died without issue in 1205. Robert le Bossu was the founder of Leicester Abbey in 1143, and Hathern was probably one of the churches given to the abbey by its founder (VCH). In or soon after 1379 the advowson was alienated to the college of St Mary de Castro, Leicester.
