Mary Ann Dille is probably descended from David Dille, b. 1718. He had many sons, seven of whom, living near Washington, PA, fought in the Revolutionary War. Shortly after 1800, several of them moved to Ohio, founded Fort Dille, later called Dilles Bottom, which was in Belmont County, Ohio. I would guess that Mary Ann was born around 1812. If you have her birthdate I might be able to find whose daughter she was.
