I haven't seen any information on the Knowltons from Caribou Maine.The Knowlton homested was built in Caribou Me. in 1774 and stood untill 1975 when it was destroied by fire. My Grand farther was Austin Knowlton he had 3 sons Eward, Arnold ane Emery. And I have much information on this line. In this line also are Holmes and Peabody.
