Ignatius Sancho
The details of his early life are not certain. He was born on a slave ship crossing the Atlantic. The ship went to the Spanish colonies in Central America. His parents did not survive long, and he became orphaned. His owner took him to London, and he eventually came to live with John Montague, 2nd Duke of Montagu and Mary, Duchess of Montagu. Sancho worked as her butler until her death in 1751.
