A series of free talks on Plymouth’s history will be held at the 1749 Court House and Museum on Tuesday nights this month. This week’s presentation will feature Wes Ennis, a photographer who teaches at Quincy College. He’ll discuss historic photographs taken in Plymouth, dating back to the 1853 daguerreotypes of Plymouth Rock. On Aug. 14, Plymouth native Ginny Davis will present “The Edmond Building: A Family Story,” on the downtown landmark that was built by her grandfather. Each session will start at 7 p.m. and finish at 7:30 p.m. For more information, contact the museum at 508-830-4075.
