3.1 million enslaved people trafficked to the British colonies

London slave-ship captain and owner, captain of one voyage by the Peggy from London in 1770 and owner-captain of a second voyage in 1772, and sailing as captain for John Shoolbred (q.v.) in at least three other voyages between 1774 and 1776. He accumulated wealth, leaving £12,000 in trust for his children as well as landed property in 1807. He was part of a slave-trading family, with his brothers James Mill (q.v.) and David Mill (at one time Governor of Cape Coast Castle, then moving to Antigua), and their cousin John Mill (q.v.). The men often appear as ‘Mills’ and sometimes as ‘Milne’, rather than Mill.
