(5-11-16)The Derrin House, a historical home built in 1810 sustained heavy damage this morning from a fire that started in the rear of the building. A passerby called in the fire at 8:48am this morning which brought the Avon, Farmington, Simsbury fire department to the scene. The fire was quickly brought under control. Since the building is located on state property the State Fire Marshal’s Office is doing the investigation. The Avon Historical Society was in the process of fixing up the house to be used as a museum.
