Cabinet photograph of a man identified on the reverse as Alexander Morse; taken by the A. F. Towne studio of 104 Main Street, Athol, Massachusetts.
He may have been the Alexander Morse (1829-1917) born in Sullivan, New Hampshire, who would marry Lucy B. Day in 1864 at Royalston, Massachusetts, not far from Athol.
Or he may have been Edward Alexander Morse (1844-1919), born in Massachusetts at nearby Hubbardston; he married Mary Elizabeth Marean in 1868. Edward, however, had moved to the Midwest by 1870, although he may have come East to visit.
Or another Alexander Morse. If you recognize him from your family photographs or research, please leave a comment or contact me directly.
