The American Textile History Museum (ATHM), located in Lowell, Massachusetts, was founded as the Merrimack Valley Textile Museum (MVTM) in North Andover, Massachusetts in 1960 by Caroline Stevens Rogers. ATHM told America’s story through the art, science, and history of textiles. In June 2016, the museum closed.
The American Textile History Museum name has its roots in a north-western town named North Andover.
The museum does have its roots in a town named North Andover, but it is not in the north-west. I think adding "north-western" in reference to North Andover threw it off.
