Ainslie, a cadet of the Ainslies of Dolphington, was bred at Bordeaux where his father (d.1773) was a merchant.
having ... served his Majesty’s government for nearly [20 years] ... in a most distinguished station, and in which he has rendered most essential services to his country, I cannot help thinking he will have a preferable claim to the support of ministry on the present vacancy than of any other person almost that may offer.
PRO 30/8/151, f. 107.
Another candidate was preferred and Ainslie had to wait until the general election, when he survived a contest at Milborne Port, the erstwhile patron of which, Sir William Coles Medlycott, had a sister married to Philip Ainslie, his barrister kinsman.
Ainslie was expected to support Pitt’s ministry and did so in silence. He voted for the assessed taxes, 4 Jan. 1798. In October 1800 he received Pitt’s circular to attend.
Ainslie died 21 July 1812 ‘in his 83rd year’, celebrated for his collection of oriental coins and prints. He left his estates in Lincolnshire and Huntingdonshire to his nephew aforesaid.
