Henry Augustus was born on 28 October 1777 at Brussels, then the capital of the Austrian Netherlands. He was the elder of the two children and the only son of Charles Dillon-Lee and his first wife Henrietta Maria Phipps. His father, the 12th Viscount Dillon, had conformed to the established religion. His mother was the only daughter of Constantine John Phipps, 1st Baron Mulgrave, an Anglo-Irish family. Thus both parents were Protestants and part of the Protestant Ascendancy in Ireland. They had married in 1776 at Brussels. He appears below as the elder of two siblings:
Henry Augustus ; and
Frances Charlotte, who married Thomas Webb, Baronet.
His mother died in 1782 when Henry Augustus was only four. In 1787 his father remarried to Marie Rogier of Mechelen, who had been an actress in Brussels and had been his father's mistress in the time before he married Henry's mother. His father's second marriage produced three children, which are:
Early life
In 1794, when he was 17 years old, Henry Augustus was made a Colonel of the newly created Catholic Irish Brigade, an unlikely employment for a Protestant that was due to his family connections. This Catholic Irish Brigade lasted only four years, being dissolved in 1798.
He seemed to have left the Austrian Netherlands and have gone to England where, in 1799, aged 22, he was a Member of Parliament for County Harwich. In 1802 he became a Knight for Mayo. His knighthood ended in 1813 upon the death of his father, when he acceded to the Peerage as the thirteenth Viscount Dillon of Costello-Gallen.
Marriage and children
In February 1807, Henry Augustus Dillon-Lee married Henrietta Browne, sister of Dominick, 1st Baron Oranmore and Browne, daughter of Dominick-Geoffrey Browne, by Margaret, daughter of the George Browne, 4th son of the 1st Earl of Altamont. The marriage took place at Castle MacGarrett near Claremorris, County Mayo, Ireland. The Brownes were an Anglo-Irish and Protestant family. The marriage produced ten children:
Gerald Normanby, who married Louisa FitzGibbon, daughter of Richard Hobart FitzGibbons, 3rd Earl of Clare, and changed his surname to hers.
Louisa Anne Rose, who married the Hon. Spencer-Cecil Ponsonby of Bessborough; and
Helena Matilda.
Emily W. Sunstein in her biography Mary Shelley: Romance and Reality writes "the literary Lord Dillon... was said to be Eliza Rennie's lover." , 1803
Later life, death, and timeline
On 9 November 1813 his father died at Loughglinn, County Roscommon, and was buried in the Dillon Vault at Ballyhaunis. Henry succeeded as the 13th Viscount Dillon, at the age of 36. He died on 24 July 1832 in London and was buried in the All Saints Church at Spelsbury. He was the first Dillon to be buried in Spelsbury. His widow died thirty years later at the Hotel Windsor, Paris, 18 March 1862, aged 73.
