Boucherett came of a London mercantile family of French origin which invested in Lincolnshire estates in the 17th century and acquired the Ayscoghe estate there by marriage. His mother-in-law’s remarriage to the financier John Julius Angerstein gave him contacts with merchant entrepreneurs and in 1795 he was in the forefront of a scheme to reopen the silt-clogged harbour of Grimsby, of which borough he had been elected high steward the year before. He was elected chairman of the company authorized by statute to carry it out (14 May 1796).
Boucherett was an unobtrusive Member. On 15 Dec. 1796, having just subscribed £5,000 to the loyalty loan, he obtained a month’s leave because of a relative’s illness. Portland, on learning from him that his attendance would involve ‘serious inconvenience or risk’, excused him, 10 Mar. 1797, there being no ‘very pressing call upon our friends’ and wished he might ‘at a future period of the session’, if applied to, ‘travel without inconvenience or danger’.
The difficulties of the Grimsby Haven Company and the struggle between company and corporation at Grimsby eventually caused a breach between Boucherett and Yarborough; and the enterprise was in some confusion at Boucherett’s death. After selling his town house in 1811, he lamented:
I feel it d—d hard to be precluded seeing my friends in the manner I like. It has been my fate to build castles on too large a scale, and I have been under the continual necessity to retrench one thing after another ... but that a liberal country establishment should become too chargeable for my income never entered my brain.
E. Suff. RO 359/43, Boucherett to Angerstein, 24 Feb. 1811.
After his death in a carriage accident, 15 Sept. 1815, his assets were barely sufficient to meet his debts. He nevertheless took the credit for the foundation of the modern port of Grimsby; he was an improving landlord who corresponded with Arthur Young on agriculture, and, according to his obituary, a ‘just, true and honourable man’, who afforded ‘an eminent example of that sterling worth and unsophisticated feeling which formerly characterized an English country gentleman’.
