This concerns the Deckers buried in the Woodard family plot in Allegany cemetery Allegany, Cattaragus County NY . I feel Mary must be a Woodard/Woodward. All else has failed but sounds like your Deckers scattered around NY and Steuben county may show up Miles. I believe he lived in Rochester with sons George Cooper Decker, a Dentist and John Nelson Decker, a Law student. Thanks. Jerry Woodard
