Edmund Quincy III (; 1681âÂÂ1737) was an American merchant and judge. He was the son of Col. Edmund Quincy II (1627-1698) II and his second wife, Elizabeth Gookin. He married Dorothy Flynt and had 7 children. Four lived to adulthood, including Edmund Quincy IV and Dorothy Quincy, who was the topic of a famous poem by Oliver Wendell Holmes Sr.
Like his father and grandfather, he was deeply involved with the affairs of the Massachusetts colony. He was a magistrate, Supreme Court judge from 1718 until his death, and a colonel in the Massachusetts militia. In 1737, he was appointed to a commission to settle the boundary between Massachusetts and New Hampshire. However, he contracted smallpox and died before his return to Massachusetts. The colony built a monument at his grave in Brunhill Fields Burial Ground in London and gave in Lenox to his family as a tribute for all of his efforts.
