John Washington Dennison was born December 4, 1860 to his father Henry Clay Joshua Dennison and his mother Eliza Ann Weedman. His paternal grandparents were Frances "Fannie" Carter and Tramel Dennison.
John married his... "distant" cousin, Martha Ellen Denison (1861-1947), and took her spelling of the surname. As one of our cousins has informed us, Benjamin Dennison is how John and Martha are connected. Ben is the father of Tramel (Tramel is the father of Henry Clay Dennison, and grandfather to John). Ben is also the father of James Reason Dennison (James is the father of William Anderson Denison, and grandfather to Martha).
