“ John Dalton, rector of Dean in Cumberland 1705–12, was born there in 1709. He received his school education at Lowther in Westmoreland, and when sixteen years old was sent to Queen's College, Oxford, entering the college as batler 12 Oct. 1725, being elected taberdar 2 Nov. 1730, and taking the degree of B.A. on 20 Nov. 1730. Shortly afterwards he was selected as tutor to Lord Beauchamp, the only son of the Earl of Hertford, the seventh duke of Somerset, and during the leisure which this employment afforded he amused himself with adapting Milton's masque of ‘Comus’ for the stage. ”
