The Capt. Timothy Johnson House is a historic late First Period house in North Andover, Massachusetts. The 2+1⁄2-story wood-frame gambrel-roofed house was built ca. 1720 by Timothy Johnson, a leading Andover resident who led Massachusetts troops in the 1745 Siege of Louisbourg. The building has a wealth of well-preserved first and second period Georgian detailing.[2]
