In further researching of the 1880 Federal Census, I came across a household of Greenberry Paxton,widower. I believe Greenberry to be Mary Ann's father! Mary Ann & Lewis Danison named one of their children "Aden Greenberry"--Federal Census has Aden's name as Freenberry Denison! A brother Josiah Hartley, as Demster Denison! Greenberry Paxton's wife was Eliza Paxton; her father Mahlon Hartley, mother: Mary Buchanan. A widow, Mary Hartley was listed in the 1880 Census with Greenberry. Ages correlate to birth dates of said individuals.
