1769 - 1829


Slave-owner on St Kitts, husband of Sophia Dupuy (q.v.), son of Isaac Dupuy and Elizabeth Dupuy nee Kemp and probably stepson of George Rigby (q.v.).

  1. Will of Isaac Dupuy of [Welbeck Street] St Marylebone [made in 1820] proved 27/01/1830. In the will, he left his property in St Christopher with 'all the negro and other slaves and cattle of every denomination, mills, mill houses...' in trust to his wife Sophia and Robert Allen of St James Westminster to secure an annuity of £1000 p.a. for Sophia during her widowhood, rising to £1500 p.a. if he died childless; in both cases, the annuity fell to £500 p.a. if she remarried. He also authorised her to raise £3000 from his estate and bequeath it separately. He left his cousin Peter Dupuy Abbott of Powis Place, Queen Square Middlesex an annuity of £200 p.a., and another cousin, Jane Akers Byam of Brussels, a share of the residual income of his estates if 2/3rds of that income exceeded the annuities charged on the estates.


  1. PROB 11/1765/151.
