 Gladstone was associated with eleven different claims, he owned 2,508 slaves in British Guiana and Jamaica and received a £106,769 payment at the time (worth £ in 2020 based on inflation, and £544.5 million in 2020 based on share of GDP).Gladstone's claim was the single largest of any recipient made by the Slave Compensation Commission and he had the largest number of slaves.His fellow Lowland Scot, James Blair made the single biggest claim for one plantation, but Gladstone's claims were spread out over multiple plantations and were worth far more.
