[2] The first, a single-story building fronting on Nagonaba, was constructed in 1880 as a grocery and dry goods store.

The store was owned by Northport native N. C. Morgan and his wife Abbie Voice.

[3] An attached two-story section was built on the rear in 1881-83; this served as the Morgans' home.

In 1996/97, the building was rehabilitated and restored to its original appearance.

[2] The Morgan–Copp–Mervau Building consists of three sections: a single-story false-front clapboard-clad section fronting on Nagonaba, a two-story false-front clapboard-clad section fronting on Mill, and a single-story cedar stickwork addition fronting onto the Nagonaba/Mill intersection.
