John Sherwin Gregory (1803–1869) was born John Sherwin Longden. His father was John Longden and his mother was Charlotte Mettam. His father had inherited Bramcote Manor from his uncle who was from the Sherwin family. He built a new house called Bramcote Hills House. When his father died in 1818 John inherited the Bramcote property and changed his surname to Sherwin thus becoming John Sherwin Sherwin. In 1829 he married Catherine Holden, daughter of Robert Holden of Nuthall Temple which was a large house in Nottinghamshire. The couple lived at Bramcote Hills House until John inherited Harlaxton Manor in 1860. The 1851 Census describes John as a "landed proprietor". When he inherited the property he changed his surname to Gregory thus becoming John Sherwin Gregory. Portraits of John and Catherine by the famous painter Thomas Phillips are shown.
