John Coffin Jones Sr. (1749 – October 25, 1829)[1] was a businessman who served as the Speaker of the Massachusetts House of Representatives from 1802 to 1803.
[1] In 1790, Jones wrote to Thomas Jefferson upon his return from France as the U.S. Minister regarding "whalefishery," which Jones considered it to "ever been the most important branch of business to this State, by furnishing its most valuable Staple export, creating a great consumption of the Produce of the Country; and thereby giving employment to a vast number of husbandmen and mechanics, whilst it proved a most extensive nursery of expert and hardy seamen.
Jones was succeeded by Harrison Gray Otis,[3] who later served as the Mayor of Boston and a U.S.
Senator from Rhode Island Christopher G. Champlin and grandson of Christopher Champlin, a merchant, ship owner and financier of Newport, Rhode Island.
Through his daughter Martha, he was the grandfather of Mary Lee Coles (c. 1842–1922), who married Harry Coster,[13] who were both prominent in New York society during the Gilded Age.
