William Plumer

William Plumer (1736–1822) was a British politician who served 54 years in the House of Commons between 1763 and 1822.

Life Plumer was the son of William Plumer and his wife Elizabeth Byde, daughter of Thomas Byde of Ware Park, and was born on 24 May 1736. He was admitted at Pembroke College, Cambridge in 1752.

Plumer was returned unopposed as Member of Parliament for Lewes at a by-election in February 1763. The Duke of Newcastle had supported his stand at Lewes because he was considered a strong candidate, and wished him to stand there at the following election. However, Plumer wanted to stand at his home seat at Hertfordshire. He succeeded his father to Blakesware and Gilston Park, Hertfordshire on 12 December 1767 and the Duke eventually agreed to release him from a commitment to stand at Lewes.

Plumer died on 15 January 1822, without issue.

Family Plumer married as his first wife Frances Dorothy Carey daughter of Lucius Cary, 7th Viscount Falkland on 12 July 1760. She died in December 1761.

He remarried to Jane Hamilton, daughter of Hon. and Rev. George Hamilton on 9 August 1791. After his death, she married, as her third husband, Robert Ward, MP, who adopted the name Plumer and moved into Gilston Park.
