↑ According to Source:Fay, Orlin Prentice. Fay Genealogy : John Fay of Marlborough and His Descendants, p. 286, in 1798, Samuel Fay gave a bond to his father Moses Fay to "perform certain obligations to Elizabeth Fay, wife of the said Moses, and to her son, John Giles, when he is 21." The marriage record in 1802 names John as John Fay Jiles. The gravestone completes the progression, giving the name as John Fay. This website represents John as the son of Moses Fay, but the naming pattern suggests he was an illegitimate child of Elizabeth Giles, who eventually took the name of his step-father.
