Manuscript 'Licence for Elizabeth Adams to Lett to Robert Adams' premises in Longhoughton, Northumberland, signed by Hugh Percy, Earl (later Duke) of Northumberland, and his wife ('Northumberland' and 'Elizabeth Northumberland').

Folio, 1 p. Bifolium. Text on recto of first leaf; docketed on reverse of second leaf. Text clear and complete. Fair, on lightly-aged and worn paper. Headed 'Longhoughton | Northumberland'. Signed at foot by the Earl and Countess. Begins 'Licence is hereby Granted to Elizabeth Adams to Lett Lett or Assign over to Robert Adams All That Messuage or Tenement and the Lands thereto belonging with the Appurtenances Lying and being in Longhoughton held of us by Lease for Twenty One yeares from Ladyday One thousand Seven hundred forty and Nine'. Robert Adams is restrained from subletting without the written permission of the Earl and Countess.
