He had two sons, Robert and Thomas. Robert Pitt who succeeded him at Boconnoc, married Harriet Villiers, third sister of John Earl Grandison. He died in May 1727, leaving two sons, Thomas Pitt, and William, afterwards Earl of Chatham. Thomas Pitt, his brother, was created Earl of Londonderry, in consequence of his marrying the heiress of Ridgeway, who had borne that distinction; this younger branch became extinct in 1764. Thomas Pitt, his son, engaged most extensively in the political speculation, for which Cornwall was then become an ample field. But, having supported the party of Frederick Prince of Wales, he failed of obtaining any of the objects to which most speculations are supposed to lead. He married Christiana, sister of George first Lord Lyttelton; by whom he left Thomas Pitt, who, on the elevation of his first cousin, William Pitt, to the chief office in the State, when under twenty-five years of age, was created Baron Camelford in Jan. 1784. He died in 1793, leaving a son Thomas Pitt, the second and last Lord Camelford, and a daughter married to William Wyndham Grenville, Lord Grenville, the present possessor of Boconnoc, having succeeded to her brother in 1804. The personal history of this young man is curious and extraordinary. He became an object of attention in Cornwall almost from his birth. On the event of his christening, in 1775, Boconoc was thrown open for public and indiscriminate entertainment, accompanied by exhibitions of the peculiar athletic exercise in which the Cornish boast to excel all their contemporaries, and to rival the Palæstræ of ancient Greece. A silver bowl of fifteen guineas was the prize of the victor (the first who threw five falls), and about fifty pounds were distributed among the vanquished. His education was conducted under a private tutor alone in the seclusion of Boconnoc; but having made an excursion to Plymouth at a time when naval preparations were in full activity, he acquired a passion for the sea so strong and rooted, as not to be overcome by all the efforts of authority or of advice. He went on the perilous voyage of discovery conducted by Captain Vancouver, and in the course of it, he is said to have experienced some harsh treatment on the part of the commmander, which seems to have stamped a new impression on his mind, rendered permanent by the long period during which it was necessarily concealed. On Lord Camelford’s return to England, the effects burst forth in acts of violence against Captain Vancouver, and from that time, On each adventure rash he roved, As danger for itself he loved.
