Countess of Pembroke's Letter

With reference to Mr. Cunningham's third query in your second number, I beg to refer him to p. 294. of Nicholson and Burn's *History of Cumberland*, 4to. London, 1727, and to Martin's *History of Thetford*, 4to. 1779 p. 292, where he will find some allusion to the Countess Anne and Sir J. Williamson; and it is possible that the Original Letter from the Countess my be amongst the MSS. which Sir J. Willimason gave to the Library of Queen's College, Oxford. The letter is quoted in Collins' *Peerage*, 5th edition, 1779, but *The World* was printed in 1768.
