David: Genealogy of Smedley Family, 1901, Gilbert Cope, Wickersham, Lancaster, PA, 1901 Historians of Chester County know well the name of Gilbert Cope. I just went back to the censuses again, and did find that Isaac and Robert Calvert were in the 1800 Greene Co. census as Colbert. Isaac appears to have one married son living with him. This may be William who married Jane Cotton. Cottons are two lines down alphabetically on that same census. Jim Ray
