Francis Barber

'Francis Barber (c. 1742/3 – 13 January 1801), born Quashey, was the Jamaican manservant of Samuel Johnson in London from 1752 until Johnson's death. Johnson made him his residual heir, with £70 a year to be given him by Trustees, expressing the wish that he move from London to Lichfield, in Staffordshire, Johnson's native city. After Johnson's death, Barber did this, opening a draper's shop and marrying a local woman. Barber was also bequeathed Johnson's books and papers, and a gold watch. In later years he had acted as Johnson's assistant in revising his famous Dictionary of the English Language and other works. Barber was also an important source for Boswell concerning Johnson's life in the years before Boswell himself knew Johnson.' https://en.wikipedia.org/wiki/Francis_Barber
