The deCoppett Estate finally came into State ownership. Rhode Island Governor Chafee toured the area in 2014. This is located on Hillsdale Road in the Hillsdale Historic District. There are numerous mill ruins (dams, head and tail races), and house & barn foundations along the Beaver River.
Fortunately we have an extensive collection of material involving this estate.
