Thomas Plummer

1749 - 1818


With John Smith and James Woodbridge, assignee of Messrs. Mure on Saxham and Caldwell estates in Hanover, Jamaica, in 1817. Identified as absentees in the Slave Register of 1817. Almost certainly Thomas Plummer of the London West India merchants Plummer, Barham and Plummer (q.v.), whose will was proved in 1818 and who was briefly MP for Ilchester in 1802-1803 until unseated for bribery. The firm's later compensation claims concerned St Kitts exclusively, but according to R.G. Thorne the firm specialised in rum and was the agent for the estates of Lord and Lady Holland in Jamaica. Thomas Plummer the MP is shown by the History of Parliament as a merchant at 48 Lime Street by 1780, which connects him as the partner of John Beach (q.v.) in Beach & Plummer earlier in his career.

  1. Will of Thomas Plummer [formerly of Fen Court afterwards of Philpot Lane and now] of Fenchurch Street [all in the] City of London [and also of Camberwell in the County of Surrey] proved 27/04/1818. His executors were his son John Plummer and William Wilson (both of whom q.v.) of Broad Street. The first half of the will is concerned with the transmission of his property at Camberwell, which he ordered be cleared of its mortgage of £2000 and put in trust for his son John and John's wife Mary for life and to be sold if the couple (or the survivor) left the house, with the proceeds placed in trust for the Mary and then John and then to their children. This is the only specific property cited in the will. His residuary heir was his son John.


History of Parliament, [accessed 08/12/2015] which opens: 'Plummer’s origins are obscure, but by 1780 he was a merchant at 48 Lime Street, London.'
