Samuel Marsh (c. 1736–1795) was a London merchant and politician who sat in the House of Commons from 1774 to 1780.
The Marsh family was closely linked in business with the Fludyer family and either Marsh or his father was in partnership with the Fludyers.
At least by 1775 Marsh was registered as a Blackwall Hall factor.
He was living at Battersea Rise when he married as his second wife Frances Elizabeth Bennet on 31 July 1773.
[1] At the 1774 general election Marsh was returned unopposed as Member of Parliament for Chippenham on the Fludyer interest, probably as a stop-gap as Samuel Fludyer's sons were still under age.
