biography text

Milsington came in for Boston after a contest in 1796, standing on the interest of his father-in-law the Duke of Ancaster. On 14 Dec. 1796 he was granted two weeks’ leave of absence for his private affairs. He voted for Pitt’s assessed taxes, 4 Jan. 1798, and is not known to have spoken or opposed government. His distractions after his wife’s death proved expensive: early in 1802 he had to pay £2,000 damages for crim. con. ‘with Mrs Jackson, daughter of Colonel Bishop’.1Edinburgh Advertiser, 12-15 Jan. 1802. Perhaps she was the Harriet Jackson Shepperton who bore him two sons in 1805 and 1807. Both entered the Bengal army. He did not seek re-election that year.

He died on the Continent 18 Jan. 1835, whereupon the title became extinct. His only son, who in 1809 became heir to the Ancaster estate once he reached the age of 25, was murdered by banditti in Italy in 1819.2Gent. Mag. (1819), i. 279.
