Although there was a house on the site when the Domesday Survey of 1086 was conducted, Cannon Hall picked up its current name from the 13th-century inhabitant Gilbert Canun. By the late 14th century Cannon Hall was in the ownership of the Bosville family of Ardsley, now a suburb in south-east of Barnsley. It was during this period that the most violent event in Cannon Hall's history took place. The Bosvilles had let the Hall out to a family (whose name has been lost), the daughter of whom was romantically involved with a man named Lockwood. Lockwood had been involved in the murder of Sir John Elland, the High Sheriff of Yorkshire. The tenant, afraid of the position in which he could find himself accommodating a fugitive, sent word to Bosville. Bosville's men arrived at Cannon Hall, where the fugitive was slain in a cruel and violent manner.
