The title of Baron Walpole was created in the Peerage of Great Britain in 1723 for Robert Walpole, eldest son of the prime minister Sir Robert Walpole, who was later created Earl of Orford and Viscount Walpole. In 1756 a cousin of the Walpole Earls of Orford was created Baron Walpole of Wolterton, also in the Peerage of Great Britain. With the extinction of the Earldom of Orford in 1797, the senior Barony of Walpole passed to Lord Walpole of Wolterton, who thus held both titles and was also created for Earl of Orford in 1806. The second Earldom of Orford became extinct in 1931, but the two baronies survive.
On Sir Robert Walpole’s retirement from the House of Commons in 1742, he was himself raised to the Peerage of Great Britain as BaronWalpole, of Houghton in the County of Norfolk, Viscount Walpole and Earl of Orford, with remainder to the heirs male of his body.
However, the Baronies of Walpole and Walpole of Wolterton survived, and were inherited by the late Earl’s distant relative, the ninth BaronWalpole and seventh BaronWalpole of Wolterton.
As of 2006 the peerages are held by the ninth Baron’s son, the tenth BaronWalpole and eighth BaronWalpole of Wolterton.
