Betty, Melvina Todd, wife of Robert R. "Preston" Todd's mothers name was Easter Dayton, and her father's name was Thomas Todd. I hope this helps you! Melvina Todd was born circa 1820 and died circa 1900, and married her cousin, RR Preston Todd July 23, 1836 in Indiana. What is your Hamilton line? My great grandparents were Henry Clay Hamilton and Ellen Fletcher from Wright County, Missouri. Do you know if they are related to your Hamilton's??
