A major lender to Manning & Anderdon and through the latter's failure a very prominent firm in the compensation process. The bank had also been entangled earlier in lending to slave-owners, and owned The Farm in Jamaica at least between 1789 and 1791 and probably until 1798; lent against the estates and enslaved people on Holland, Fish River and Petersville plantations in Jamaica in 1824, buying additional enslaved people with co-mortgagees for Holland in 1830; and were mortgagees on Friends estate in British Guiana.
