Hello, The old Shannon Cemetery which is located on the old W.J. Smith Wood Preserving Co, in Denison, I surveyed in 1978. It showed a James B. Shannon born April 25, 18? couldn't read. Died Sept 11, 1849. Nancy Shannon born June 7, 1814 and died June 10, 1848 they were on the same stone. I lived at that time at 1531 W. Main st. We lived on part of that land that the Shannon's owned. Gay Nix
