I am seeking information on Samuel DANNISON of Allegany County, Maryland. His will indicates he died there about 1824. He is listed in the 1800 and 1810 census. A son with the same Christian name is listed in the 1850 census there. I believe he had the following sons: Jared, John, and Frederick. Frederick died in Allegany County about 1815. Jared and John moved their families to Perry County Ohio about 1817.
