Horace W. Goodwin (September 11, 1787 - May 14, 1864) was a jeweller and silversmith in New Britain, Connecticut, and Vermont. As the son of Allyn Goodwin and the great-great-great-great-grandson of Ozias Goodwin, an original founder of Hartford, Connecticut, he learned the trade and returned to Hartford in 1811. He opened a jewelry store on the west side of Main Street, on the ground later occupied by the building of the Connecticut Mutual Life Insurance Company, for several years in partnership with his brother under the firm name of H. & A. Goodwin. He remained there until 1852, when he engaged in the sale of music. He was a prominent member of the Masonic fraternity, and, having a liking for military life, was one of the organizers of the "Putnam Phalanx" in 1858 to escort Thomas H. Seymour on his return from Hartford after a long career in public service as the Minister to Russia.
He had married Mary Ramsey (Oct. 4, 1789 - Sept. 6, 1858) for a first marriage on November 29, 1812. She was the daughter of Jonathan Ramsey and Mary Chadwick. He married for a second time on February 1, 1860 to Phebe C. Hayman, the widow of William Hayman of Salem Massachusetts.
