Winchcombe Henry Hartley

Winchcombe Henry Hartley (1740–1794) was a British politician who sat in the House of Commons between 1776 and 1794.

Hartley was the second son of David Hartley, physician and philosopher and his second wife. Elizabeth Packer, daughter of Robert Packer MP of Bucklebury and was born on 20 May 1740. He inherited the estates in Berkshire and Gloucestershire of his uncle Henry Packer of Bucklebury in 1746. He entered Lincoln's Inn in 1756 and matriculated at Christ Church, Oxford, on 11 November 1757. His first wife was called Harriet. He married secondly Mary Jenkinson, widow of St. Anne’s, Soho, on 30 August 1777.

Hartley was returned Member of Parliament for Berkshire in a by-election on 21 February 1776. He was returned again in the 1780 without a contest. He followed his brother David’s politics and consistently opposed North’s Administration. The Public Ledger wrote in 1779, that he “sometimes speaks, which he had better let alone; his speeches, though not as long as those of his half-brother, are flat and empty.” In 1784 he was defeated in Berkshire. He also stood for Gloucestershire, but retired after the first day’s poll.
