Edna Pearl Clay Goodspeed (1884-1963) was an active member of the Daughters of the American Revolution who served as a nurse overseas during World War I. Her ancestors included Revolutionary War soldiers Charles Mathewson, Capt. Aaron Coe, David Clay and Capt. Samuel Cobean, and tailor Otis Madison, who pioneered a new system for garment measuring and cutting in the early nineteenth century. At the time of Goodspeed's death she was preparing a history of the the Clay family of Ohio and related Pennock, Mathewson, Madison, Pontius and other families, entitled Some Ohio Pioneers. Her writings, notes and research materials were given to genealogist Helen B. (Blanchard) Hartman with whom Goodspeed had been collaborating before her death.
