Thomas Lutwidge (c. 1670-?) of Whitehaven was an extensive merchant and ship-owner who served as high-sheriff of Cumberland. He was the father of Charles Lutwidge, the Treasury's anti-smuggling enforcer on the Isle of Man, and the grandfather of Admiral Skeffington Lutwidge, who was a friend of Nelson. The Lutwidge family's commercial and official connections linked Whitehaven closely to the Isle of Man.
