I too am looking for Roach of Grant City, MO. Great-great grandfather was John Roach who married Mary Jane Duncan April 3, 1845 in Jasper, MO. They had David Roach (my great grandfather)and Ben Roach. David married Eliza Elizabeth Thomas. Her parents were Joseph Thomas and Mahala Fletchall. Any connection please e-mail me at hulbert@tcworks.net
