Baron Heytesbury, of Heytesbury in the County of Wiltshire, is a title in the Peerage of the United Kingdom. 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. His son, the second Baron, sat as Member of Parliament for the Isle of Wight. On his marriage in 1837 to Elizabeth Holmes, daughter of Sir Leonard Worsley Holmes, Lord Heytesbury assumed the additional surname of Holmes. As of 2010[update] the titles are held by his great-great-great-grandson, the seventh Baron, who succeeded his father in 2004.
The Baronetcy, of Heytesbury House in the County of Wiltshire, was created in the Baronetage of Great Britain on 4 July 1795 for the first Baron father, William à Court. He was a colonel in the army and represented Heytesbury in the House of Commons. His father, William Ashe-à Court, was a general in the army and also sat as a Member of Parliament for 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 Holmes à Court, now one of Australia's richest women. Their vast business interests are managed through Heytesbury Pty Ltd, a company named after the family peerage. The current heir presumptive, Peter Holmes à Court, belongs to the Australian branch of the family.[1]
The heir presumptive is Peter Holmes à Court (b. 1968)[2]
