My Grandmother's grandparents were John Swank Mercer and Susie (Coy) Mercer, Susie's parent's were Henry Coy and Matilda (Hickman) Coy, and Henry's parent's were Daniel Coy and Susan (Minleir) Coy, and that's as far as I can get. If anyone has any information, please e-mail me. My grandmother was born in 1914, so I'm guessing Daniel Coy was probably born in the 1820's or 1830's. My grandmother was born in Missouri if that helps any.
