Samuel apparently married his brother James' wife Alice after James died (phone conversation between Edward A. Dunscombe and Philip B. Stewart., 6 Sabal Ct., Sewall's Pt., Stuart, Fl., about 1990).
He owned and occupied the east half of lot No. 6, which was located about forty rods north of Fort Morris. "The site of the homestead has been a pasture for many years, but could the old turf speak and tell the tale of pioneer life there, more facts would be known and more history written." Came to Colrain, Mass. prior to 1751. Sold the home lot August 24, 1770, when Samuel and his wife Alice were of Shelburne, Mass. April 20, 1780, when they sold the land in the second division, they were of Colrain. This is the last mention of him. He probably died at or near Salem, N.Y., prior to 1800, when we catch the last glimpse of Alice, apparently then a widow, "living at Merrimans" (probably the family of a daughter) and evidently soon to move with that family still westward "to the Ohio." It is supposed that she died in or near Beaver, Pa. She is said to have been called a "whole divine," good Scotch doubtless in theology. A Spartan mother who gave to her offspring their full share of the ancestral love for emigration, and to her sons that staunch and fearless patriotism that flowed so naturally in her veins
