Plymouth was a parliamentary borough in Devon, which elected two members of parliament (MPs) to the House of Commons in 1298 and again from 1442 until 1918, when the borough was merged with the neighbouring Devonport and the combined area divided into three single-member constituencies.

Major General Charles Trelawny, also spelt 'Trelawney', was an English soldier from Cornwall who played a prominent part in the 1688 Glorious Revolution, and was a Member of Parliament for various seats between 1685 and 1713.
