The Croydon Citizen by Sean Creighton is a useful source of local information only occasionally Thornton Heath exactly but still of interest. e.g.
“James Ivers inherited Barlow’s property. Because of big losses on his Grenada estates, he sold the Addington estate in 1802-3. He went on to receive compensation for 262 slaves on Grenada and 253 on two estates on Jamaica, continuing to own them and leaving them to his sons. His son James was born at Addington in 1798, and received a share of the compensation for 366 enslaved people on three estates on Antigua. Thomas Coles bought the Addington estate. His son, who lived at Thornton Heath, shared compensation on 127 slaves on Dominica. ”
