The Problem Two published sources differ regarding the parents of Levi Merrill:
Levi's family Both sources agree that Levi [Jr.] married Sylvia Leavitt, and had children: Levi, Lucy, Tabitha, Tyler, Luther, Calvin, Jacob, Theodosius, Joanna, Alvah, and Sylvia. Merrill Memorial also lists sons Sariah and Humphrey.
Levi and Sylvia were married in 1779 (Maine Marriage Records, Pre 1892 Delayed Returns; Roll 75). Levi [Sr.], who was supposedly the father of the groom, would have been 29 years old, making him a contemporary of the groom, rather than his father.
Summary The Levi Merrill who married Sylvia Leavitt is not the son of Levi Merrill and Hannah Bean. He is most likely the son of Daniel Merrill and Elizabeth Clough.
