you've very welcome! i just thought to look up the 1880 date and found this page, which lists the 10 jun 1880 as his graduation date:

http://www.history.navy.mil/books/callahan/reg-usn-s.htm

"Smith, Albert Edward.
Cadet Engineer, Naval Academy, 14 September, 1876. Graduated 10 June, 1880. Assistant Engineer, 10 June, 1882. Resigned 7 December, 1886."

found a couple other mentions of him, including here, where he's listed as being from wisconsin -- and gives his date of admission and AGE at admission! admitted sept 14 1876 age 17 years 8 months, which puts him born dec 1858 or jan 1859.
