I am kinda stuck. I am trying to trace the Roosa line. I have finally traced John Roosa's (my ggggrandfather which was born in chemung co.) parents. His father John Roosa was born in Ulster Co. but I don't know the year. John Jr.'s Mother is Julia Roosa (born in 1819) and was buried next to John Jr. in chemung Co. There is no sign of John Sr.'s grave. Where do I go from here? Is there a way to track John Sr. in Ulster Co.?
