Sitwell’s father Francis Hurt inherited the immense wealth of his kinsmen the Sitwells in 1776 and assumed their name.
In the autumn of 1795 Sitwell informed the Duke of Portland of his wish for a seat in Parliament. On 9 May 1796 the duke invited him to London to discuss the matter.
He died 4 July 1811 of gout in the head. He was seen twice after his death, at Sheffield and Renishaw, but not in the House of Commons.
