Baron Heytesbury

It was created in 1828 for the prominent politician and diplomat Sir William à Court, 2nd Baronet, who later served as Ambassador to Russia and as Viceroy of Ireland.

The baronetcy, of Heytesbury House in the County of Wiltshire,[4] was created in the Baronetage of Great Britain on 4 July 1795 for the first Baron's father, William à Court.

His father, William Ashe-à Court, was a general in the army and also sat as a Member of Parliament for the rotten borough of Heytesbury.

A junior line of the family has attained fortune and fame in Australia, thanks to the business empire of Robert Holmes à Court, who was of South African birth, and his Western Australian wife Janet, formerly one of Australia's richest women.

Their vast business interests are managed through Heytesbury Pty Ltd, a company named after the family peerage.
