Abney Hastings’s paternal ancestors had long been prominent in Leicestershire. His father, the illegitimate son of Francis Hastings, 10th earl of Huntingdon, secured rapid promotion in the army and rose to the rank of general. Huntingdon bequeathed him property worth £2,000, which he consolidated by marrying the Abney heiress in 1788. He was created a baronet in 1806.
Abney Hastings voted against Catholic relief, 6 Mar. 1827. A week later he wrote to advise the home secretary Peel of the ‘principal charges’ about to be levelled against the corporation of Leicester and solicited his help in defending it.
Abney Hastings maintained a London residence at 6 Cavendish Square for the rest of his life. Writing to Sir Charles Imhoff in 1838 he enthused over the London season and warned against the perils of retiring to the country:
If you stay much longer ... they’ll make a grand juryman of you, or what is worse, a high sheriff, or what is worse still, a Member of Parliament, or what is worse of all, steward of some country ball. We shall have you smelling of hay and turnips, and talking learnedly of fat sheep. Should you ever venture among us again it will be as a judge of some Smithfield cattle show.
Add. 29191, f. 263.
He devised the former Huntingdon estates to his cousin the 4th marquess of Hastings, and the Willesley property to Hastings’s eldest sister Lady Edith Maud Clifton, suo jure countess of Loudon. He died in July 1858.
