Frederick North, second earl Guilford, was born April 13, 1732, the eldest son of Francis North, first earl of Guilford, and Lady Lucy Montagu, who died in 1734. The father remarried in 1736, and Frederick became the stepbrother and lifelong friend of William Legge, second earl of Dartmouth. North studied at Eton and Trinity College, Oxford, and in 1754, became a Member of Parliament for Banbury. In 1756, he married Anne Speke, with whom he had seven children. The Duke of Newcastle appointed North to the office of Lord of the Treasury in 1759, which he held until 1765. In 1766, he became Joint Paymaster of the Forces in Pitt's ministry, and the next year, succeeded Charles Townshend as the Chancellor of the Exchequer. North became the unofficial leader of the House of Commons in January 1768, a position made official later that year. In February 1770, he became Prime Minister, retaining the office until his resignation in March 1782. He died on August 5, 1792.
