The circumstances in which Beauclerk was returned for Thetford are described by Horace Walpole in a letter to Lady Suffolk:
We are more successful, Madam, than I could flatter myself we should be. Mr. Conway ... has negotiated so well, that the Duke of Grafton is disposed to bring Mr. Beauclerk in for Thetford. It will be expected, I believe, that Lord Vere should resign Windsor in a handsome manner to the Duke of Cumberland.
The Beauclerk family and the Duke of Cumberland both had influence at Windsor, and it seems clear that Grafton (who was closely connected with Cumberland) provided Beauclerk with a seat at Thetford in order to avoid a contest at Windsor.
Beauclerk’s conduct in Parliament shows that he felt under no obligation to Grafton. In Bute’s list of December 1761 he is marked ‘pro’, with the note ‘Dorset’—there was an old connexion between his father and the Duke of Dorset;
On 22 June 1767 Sir William Meredith suggested Beauclerk to Portland as ‘an excellent man’ to contest Leicester at the forthcoming general election. Beauclerk acknowledged, wrote Lord George Cavendish to Portland on 16 August, ‘that he should like of all things to come into Parliament under your Grace’s auspices, though perhaps he should not like to be beholden to any other person for a seat’; yet ‘he was cautious of venturing where he could not see his way tolerably clearly’, and ‘could not be sure that he might not be drawn into an expense that would by no means agree with his circumstances’.
The Duke of Grafton, as Lord Bessborough tells me, does not choose Mr. Beauclerk at Thetford because he votes constantly with us, and Lord Bessborough thinks with reason that we ought to take care of him.
Nothing had been done about finding a seat for Beauclerk when, at the beginning of February, Newcastle had from a friend the disposal of a safe seat for £2,000.
Beauclerk henceforth voted consistently with the Rockinghams, and attended the Opposition dinners at the Thatched House in May 1769 and January 1770. But he never belonged to the party’s inner circle, and seems to have taken little interest in politics. There is no record of his having spoken in the House, and he did not stand in 1774.
Sir Henry Etherington, whose ward subsequently married Beauclerk’s eldest son, wrote about Beauclerk on 29 Apr. 1788, after he had succeeded to the dukedom:
I believe he can give his son nothing, his finances being in a ruined state that he was obliged to live abroad before he came to the title. He has been known at Newmarket. The Duke of Saint Albans is always hereditary Grand Falconer of England with a grant of £25,000 [sic] a year with it. This is all I believe that belongs to the title, and the Duke has nine children to provide for without any money to do it.
And from other correspondence it is clear that the lady’s fortune was one of her chief recommendations in the Duke’s eyes.
Saint Albans died 9 Feb. 1802.
