Sir William Abdy, 7th Baronet

Sir William Abdy, 7th Baronet (1779 – 16 April 1868), was a British politician and baronet. He was born in Marylebone, London, as the only son of Sir William Abdy, 6th Baronet, and his wife Mary Gordon, daughter of James Gordon.

Abdy received his education at Eton College and subsequently attended Christ Church, Oxford, where he matriculated in 1796. In 1803, he inherited the baronetcy from his father, becoming the 7th Baronet.

His career included military service, beginning with his promotion to lieutenant in the South Essex Militia in 1798. He also served as second lieutenant of the Southwark Volunteers. In 1817, Abdy entered politics as a Member of Parliament for Malmesbury, serving until 1818.

Abdy was a co-owner of three estates located in Antigua and St Vincent. During the 1830s, following the British government's emancipation of slaves, he received compensation totaling approximately £13,000 for the emancipation of over 300 enslaved individuals on his and other plantations.

Regarding his family, Abdy married Anne Wellesley on 3 July 1806. Anne was the eldest daughter of Richard Wellesley, 1st Marquess Wellesley, and Hyacinthe-Gabrielle Roland. She was born illegitimate but later legitimated. Their marriage took place at Hyde Park Corner. During their marriage, Anne Wellesley became the lover of Lord Charles Bentinck. Consequently, William Abdy and Anne Wellesley were divorced in 1816.

William Abdy did not remarry after his divorce. He died at the age of 89 in Hill Street, London. His death marked the extinction of the baronetcy, as he left no legitimate issue.
