John Lace, Deemster for the southern district of the Isle of Man and afterwards First Deemster.

He came to the bench from the House of Keys. He was a member of the House in 1791, and it was he who certified the true copies taken from its journals for the Commissioners of Inquiry on 28 September that year, including the resolution of March 1765 by which the Keys had appointed commissioners at the Revestment. In July 1793 he was one of the witnesses to Bishop Claudius's instrument executed at St John's Chapel, with Edward Christian, John Crebbin and Henry Corlett.

By the end of the century he was Deemster for the south and living at Castletown, while John Frissell Crellin held the northern district from Orrisdale. Feltham, who set the two down side by side in his tour, remarked that he had not had the honour of knowing the former, though he was warm about the Crellins' hospitality.

His most public moment came in 1809 and it began in a theatre. Major-General William Stapleton, in what was described as a mere frolic, pushed a person at the theatre in Douglas, and an affray followed. Stapleton afterwards preferred charges against his Honour John Lace, by then His Majesty's First Deemster, and the Home Secretary ordered an investigation. Stapleton's case was printed, dated 21 October 1809, and runs to thirty pages.
