George the Second, by the grace of God of Great Britain, France, and Ireland king, defender of the faith, and so forth, to the sheriff of Norfolk, greeting.  Command Abraham Barker, Esquire, and Cecilia, his wife, and John Barker, Esquire, that justly and without delay they perform to David Edwards, Esquire, the covenant made between them of two messuages, two gardens, three hundred acres of land, one hundred acres of meadow, two hundred acres of pasture, and fifty acres of wood, with the appurtenances, in Dale; and unless they shall so do, and if the said David shall give you security of prosecuting his claim, then summon by good summoners the said Abraham, Cecilia, and John, that they appear before our justices, at Westminster, from the day of Saint Michael in one month, to show wherefore they have not done it: and have you there the summoners, and this writ. Witness ourself at Westminster, the ninth day of October, in the twenty-first year of our reign.
