Mark, There is an Atlas dated 1797-1880 for Adams County. I don't know if this helps. It is also sold by the Sycamore Chapter DAR at the Library, but theirs not many left. They cost $32.50 plus $1.95 tax if you live in Ohio & also postage of $4.00. Thanks, Delsey Knoechelman Adams Co. Genealogical Soc., Vice President & Newsletter Editor
