William Wellesley-Pole, 3rd Earl of Mornington, GCH,PC,PC (Ire) (20 May 1763 – 22 February 1845), known as Lord Maryborough between 1821 and 1842, was an Anglo-Irish politician and an elder brother of the Duke of Wellington. His surname changed twice: he was born with the name Wesley, which he changed to Wesley-Pole following an inheritance in 1781. In 1789 the spelling was updated to Wellesley-Pole, just as other members of the family had changed Wesley to Wellesley.
Origins
The young William Wesley aged 14, painted in 1777 by Benjamin West
Wesley was educated at Eton (1774–1776) before entering the Royal Navy as a midshipman, serving in the Navy between 1777 and 1783; most notably aboard HMS Lion, a new ship launched in 1777, at the Battle of Grenada of 1779.[1]
Pole inheritance
Due to the debts of their father, the Wesley family entered into financial stringency. This was partially alleviated following the death in 1781 of the childless William Pole, of Ballyfin in Ireland, his godfather and the husband of his great-aunt Ann Colley, who bequeathed his estates to Wesley, on the condition which was usual in such situations that he should adopt the surname "Pole".
Pole was descended from Peryam Pole, third son of the antiquary Sir William Pole (1561–1635) of Shute House, Devon, a brother of Sir John Pole, 1st Baronet. He had married Ann Colley, the sister of Wesley's grandfather Richard Wesley, 1st Baron Mornington (1690–1758). This Wesley had been born Richard Colley, but had changed his name in 1728, following an inheritance, to Wesley. Thus it was that in 1781, in accordance with the Will of his great-uncle William Pole, Wesley changed his name to Wesley-Pole.[2]
Lady Mary Charlotte Anne Wellesley (1786–1845), who married Sir Charles Bagot, Bart., G.C.B., on 22 July 1806. The couple had four sons and six daughters. The family accompanied their parents to Canada on the appointment of Sir Charles Bagot as Governor-General of British North America, on 12 January 1842. As the wife of a Governor-General in Canada, Lady Bagot assumed the title of 'Her Excellency', in Montreal in August 1842. After her husband's death at Kingston, Ontario on 18 May 1843, she accompanied the remains to England. She died in London on 2 February 1845.[4]
