Powell’s family came from Pembrokeshire,
But on 12 Aug. 1764 Lord Harcourt wrote to George Grenville:
I saw Mr. Harcourt Powell this morning. We had a great deal of Isle of Wight conversation, and as he seemed desirous of talking over those affairs with you, I thought it advisable to tell him that I was persuaded you would give him a hearing ... In general he seems well disposed, he declares against a peevish opposition, and professes the strongest duty and attachment to the King, and spoke very highly of you, and declared even that he had received civilities from you, which he had not forgot. He acknowledged fairly to me that he never repented so much of any thing, as being of Wildman’s Club. The deputy government of the Isle of Wight, he declares, is no object and what he would not accept. I sounded him to find out what was his object and cannot find he wants any thing. To be considered as a man of consequence, and to have a considerable interest in the Island of Wight, seem to weigh most with him.
And again on 26 Aug.:
I shall write to Mr. Powell very soon, and you may be assured, that no caution shall be wanting that may prevent a bad use being made of it; as I really have a great regard for Mr. Powell, and as I am in great hopes, that he may not only be brought to have a right sense of things himself, but be the means of doing no inconsiderable service, I shall urge every argument that can with decency be urged to induce him to support his Majesty’s Government and your Administration.
By September 1764, Powell was transacting Government business with the Rev. Leonard Holmes, Lord Holmes’s nephew and heir.
He died 26 Feb. 1782.
