In the History of the Town of Whately, Mass is reference to "an Indian known as Samson Johnson or Johnson Samson." He had three sons- David, Cyrus, and Eph (Ephraim), who worked on farms in town and in nearby Conway and Deerfield "as late as 1835." It was noted that Cyrus was "half negro." The book's author related that after Cyrus's birth, Johnson tied up his Indigenous wife, beat her, and "gave her a lecture that I have often heard, but will not relate here."
Before 1815, Samson Johnson and at least two of his sons moved to Conway. The 1820 federal census shows that David was the head of household with two "Free Colored" males between the ages of 26 and 44, one female aged 14-25, and one female under age 14. David would have been one of the males and the other might have been Eph, as the 1860 federal census shows a Cyrus Johnson as head of a household in Van Buren, New York.
