History of the Town of Middleboro, Mass, 1906
"A few years ago when the highway was straightened and repaired, remains were found. When the skeleton measured by Dr. Morll Robinson and others, it was found that the thigh bone was four inches longer than that bone in an ordinary man, and that he had a double row of teeth in each jaw. His height must have been at least seven feet and eight inches."
