Sir John Molesworth, 4th Baronet

Sir John Molesworth, 4th Baronet (1705–1766) of Pencarrow, Cornwall, was a British landowner and Tory politician who sat in the House of Commons between 1734 and 1761.

[1] At the 1734 British general election Molesworth was returned unopposed as a Tory Member of Parliament for Newport on the interest of his brother-in-law, Sir William Morice.

He did not stand at the 1741 British general election but was returned as MP for Cornwall at a by-election on 12 December 1744 in succession to his wife's brother-in-law, Sir John St Aubyn, 3rd Baronet.

[2] Molesworth was alarmed at the threat of a contest at the 1754 British general election but it did not materialize and he was returned unopposed.

[3] Molesworth started the construction of Pencarrow in the 1760s, extending a large older house on the site.
