Lieutenant-Colonel Ayscoghe Boucherett JP DL (/ˈæskju/; 16 April 1755 – 15 September 1815) was a British landowner, businessman and politician who served as Member of Parliament (MP) for Great Grimsby from 1796 to 1803.

[4] The elder Boucherett's daughter, Mary, had married Michael Barne of Sotterley, Suffolk, an army officer and a member of parliament for Dunwich.

[8] The Boucheretts had one son and three daughters: Boucherett paid for the construction of a new family seat in 1790; Willingham House was a larger and grander mansion than the family's previous seat closer to Willingham, and was constructed in the neoclassical style, most likely by Robert Mitchell, two miles west of the earlier house.

[12] The family's connection with the art connoisseur John Julius Angerstein led to them becoming acquainted with certain artistic circles in the late eighteenth century; most notably, they established a close friendship with the portrait painter Sir Thomas Lawrence, who would go on to be President of the Royal Academy.

[15][16] A separate study of the three daughters, Emilia Mary, Maria and Juliana, was sold by the auction house Christie's in 2012 for £121,000.

[17] In the 1790s, Boucherett began to rise through Lincolnshire's civic and mercantile circles, especially in the north of the County, where the family had their seat; his connexions helped him to become involved with a group of businessmen planning to reopen and expand Grimsby's harbour.

[2] Yarborough, Boucherett's patron, was an opponent of the administration of William Pitt the Younger and supported the Duke of Portland during the 1790s.

[23] Although opened in 1800 at the cost of £100,000,[24] the new harbour at Grimsby failed to attract the levels of trade the company had projected, caused largely by a lack of inland transport networks.
