Henry Augustus was born on 28October 1777 at Brussels, then the capital of the Austrian Netherlands. He was the eldest son of Charles Dillon-Lee and his first wife Henrietta Maria Phipps.[2] His father was the 12th Viscount Dillon, who had in 1767 conformed to the established religion.[3]
Henry Augustus's mother died in 1782 when he was four.[5] In 1787 his father remarried to Marie Rogier of Mechelen,[6] who was an actress in Brussels and had been his mistress before he married Henry's mother.[7] Henry Augustus had three half-siblings, a brother and two sisters, who were born from his father's second marriage.
Henry Augustus was brought up by his uncle Constantine Phipps, 2nd Baron Mulgrave.[8] In 1794, when Dillon-Lee (i.e. Henry Augustus) was 17, he was made the colonel of a regiment in the newly created Catholic Irish Brigade, an unlikely employment for a Protestant, that was due to his family's military connection to the Irish Brigade. This Catholic Irish Brigade lasted four years, being dissolved in 1798. On 21 October 1795 Dillon-Lee immatriculated at Christ Church, Oxford.[9]
In 1799, aged 22, he contested and won a by-election caused by the death of Richard Hopkins MP for Harwich Borough, County Essex. This was during the 18th and last parliament of Great Britain, summoned in 1796 to meet at Westminster on 12July 1796. It continued without a general election as the 1st Parliament of the United Kingdom, 1801–1802. He sat therefore until 29June 1802 when parliament was dissolved.[10]
In the general election of 1802 he was elected for one of the two seats for County Mayo in the House of Commons of the United Kingdom.
In 1805 he raised a new regiment in Ireland, called the Duke of York's Irish or the 101st Regiment of Foot. He owned the regiment and hired out its services to the British army under a letter of service.
In February 1807 at Castlemacgarrett, Dillon-Lee married Henrietta Browne, sister of Dominick, 1st Baron Oranmore and Browne, daughter of Dominick-Geoffrey Browne, by Margaret, daughter of George Browne, 4th son of the 1st Earl of Altamont. The marriage took place at Browne ancestral Castle MacGarrett near Claremorris, County Mayo, Ireland. The Brownes of Mayo were an Anglo-Irish, Protestant family.[11] Henrietta's niece was married to George A. Lawrence, author of Guy Livingstone.
Dillon-Lee's regiment was ordered to Halifax, Nova Scotia, Canada, to where he also took his wife and where his eldest child was born in 1807.[12]
On 9November 1813 his father died at Loughglinn House, County Roscommon, and was buried in the Dillon Vault at Ballyhaunis.[24][25] Henry succeeded as the 13th Viscount Dillon, at the age of 36, he also inherited Ditchley House, inherited from the Earl of Lichfield (Lee family).
Lord Dillon, as he now was, lived with his wife and children in Florence, Italy in the late 1810s and in London in the 1820s where he seems to have had an affair with the writer Eliza Rennie,[26] and where he wrote his two historical novels, Maltravers, published in 1822, and Rosaline de Vere, published in 1824.
Dillon died on 24 July 1832 in London and was buried in the All Saints Church at Spelsbury.[27] He was the first Dillon to be buried in Spelsbury. His widow died thirty years later at the Hotel Windsor, Paris, 18March 1862, aged 73.
