St Leger St Leger, 1st Viscount Doneraile (born St Leger Aldworth; died 15 May 1787), was an Anglo-Irish politician and peer.

Life and career[edit]

He was the son of Richard Aldworth and the Hon. Elizabeth St Leger.[1] Through his mother, he was a grandson of Arthur St Leger, 1st Viscount Doneraile.[1]

He was given the name of St Leger Aldworth at birth, but he legally changed his surname to St Leger on 9 May 1767,[citation needed] when he succeeded to the Doneraile estates upon the death of his uncle, Hayes St Leger, 4th Viscount Doneraile (1702–1767).[1] Like several other members of his family, he served in the Irish House of Commons as the Member of Parliament for Doneraile, sitting between 1749 and 1776.[1]

On 2 July 1776, St Leger was created Baron Doneraile in the Peerage of Ireland.[1] On 5 January 1785, he was created Viscount Doneraile, of Doneraile in County Cork, the title previously held by his maternal relations.[1]

He married Mary Barry, the daughter of Redmond Barry, and together they had six children.
