Francis Humberston Mackenzie of Seaforth (1754-1815) was a Highland proprietor in what has become known as 'The First Phase of Clearance', was governor of Barbados (1801-6) in the sensitive period immediately before the abolition of the British slave trade and was himself a plantation owner in Berbice (Guiana). It is suggested that his concern for his Highland small tenants was paralleled by his ambition in Barbados to make the killing of a slave by a white a capital offence, by his attempts to give free coloureds the right to testify against whites and by his aim to provide good conditions for his own enslaved labourers in Berbice.
