Does anyone know A. Jackson Cowan (b. about 1815) and wife Maria(h)? They were in Washington County, VA 1840 census and 1860 (not too sure where in 1850). They appear to be parents of Newton Cowan (b. ca 1841); Samuel (b.ca 1843); Harriet, James, David, Mary and George. It appears Jackson may be son of James and Margaret Cowan but only circumstantial at present ... Anyone know this family? Gary
