Thank you very much for your reply. I am a descendent of Jacob Groscost, also, through Jacob and Elizabeth's daughter, Catharine. My purpose in trying to locate the graves of James and Elizabeth Calvin was to obtain dates from the grave markers and to help establish and prove my lineage. Are you aware of the existance of any family Bible or any documentation that would support or verify relationships? Being a member of DAR, I am interested in establishing my lineage from Jacob Groscost.
