Jeremiah Colegrove (1758–1836): Prominent farmer and manufacturer in New England, born to William Colegrove in Scituate, Rhode Island and grandson of Stephen Colegrove. Jeremiah was a captain in the American Revolution and helped to found the city of North Adams, Massachusetts. He married Lydia Waterman and had at least one recorded son, Jeremiah Colegrove, Jr. The Daily News of Troy, NY said of North Adams in 1890. “The real prosperity of the Town had its birth in the introduction of the first machinery for carding wool, in 1801, when one carding-machine was put into Jeremiah Colegrove’s Grist-mill… Captain Colegrove erected a two-story mill on the east bank of the south branch, where the Phoenix mill now stands, for wool carding, cloth fulling, and cloth dressing; and he successfully carried on the business for fifteen years, despite the energetic competition of David Estes, who succeeded Roger Wing in the River Street mill…" Along with Benjamin Sibley and others, he formed "The Adams North Village Cotton & Woollen Manufacturing Company".
