In page Beckenham:

"

By the time of the arrival of the Normans, the manor of Beckenham encompassed much of what is modern Beckenham, with other areas covered by the estates of Foxgrove Manor, Kelsey and Langley. Although William the Conqueror's half brother, Bishop Odo, was overlord of all of Kent the manor of Beckenham was held or enfeoffed to Anschil of Rochester.[4] The manor became divided but eventually rejoined under the St. John family until Frederick St. John, 3rd Viscount Bolingbroke sold most of the manor to John Cator the younger in 1773. The manor house and its grounds had been exchanged with Peter Burrell, Lord Gwydir in 1757.[citation needed]
