Letter from George Booth, 2nd Earl of Warrington 22 July 1727. G.B. apologizes for being unable to wait on P.L. next week with his uncle [Robert Booth], Dean of Bristol, but is hurrying to London on urgent business. G.B. will agree to whatever P.L. decides re disposal of money in Mr Legh of High Legh's hands.
Letter from George Booth, 2nd Earl of Warrington, 28 June 1729. G.B. has sold the reversions of several tenements in Warrington lately to raise cash, and is about to sell more. He has no intention of selling the Royalty, though he believes it will be sold after his death, but if he ever changes his mind P.L. will have first refusal.
Letter from George Booth, 2nd Earl of Warrington, 19 May 1738. G.B. hopes to visit P.L., his nephew and his new wife at Lyme next week, and invites them to Dunham, but asks P.L. to prepare his niece "for such unusual reception as I fear she'le meet with, for I yet perceive no likelihood of change in a Temper that has ever been stubborn and obstinate for above 36 years" [i.e. G.B.'s estranged wife Mary].
