Samuel and Louisa Densmore Williams are listed in 1850 census for Burlington, Bradford County, PA. Does anyone there see mention of them after that? I have not been able to find cemetery listing or obit. They are my late husband's great-grandparents. His grandparents,Charles Cornelius and Elizabeth (Lizzie) Cloose lived in Westfield, Tioga County, PA.( No mention there of elder Williamses). Their son,my husband's father (Edwin Samuel Williams) was grandson of Charles C., who served in Union Navy in Civil War. What could have happened to Sam and Louisa sometime after 1850? Our 16-year-old grandson Samuel Williams would like to know all about his ancestor! Alice H. Williams
