 Part of the indenture required Rose to see to Haynes's education, and by accompanying Rose to church, he became exposed to Calvinistic religious doctrine, including the works of Jonathan Edwards, George Whitefield, and Philip Doddridge, who all became strong influences on Haynes' religious outlook.According to Haynes, while David Rose fulfilled his indenture obligations to Haynes, Rose's wife Elizabeth (Fowler) Haynes (d. 1775) was especially devoted to his upbringing, to the point of treating him as though he was her own child.Freed in 1774 when his indenture expired, Haynes joined the minutemen of Granville.
