CARL RUSSO/Staff photo. WINDHAM MAGAZINE: Jean Manthorne of the Windham Museum holding the Proctor family's history on a sampler dating back to the 1700's. There are some interesting little artifacts in the Windham Museum which is inside the Armstrong Memorial Building. The artifacts are housed in the former home of the library in a really sturdy building that the town forefathers wanted to last for future generations - so it's not just housing history but part of it to. 2/21/2015.
