I believe this headstone belongs to one of my ancestors, Julianna (Savercool) Erway. She was married to Conrad Erway and they had 13 children together. Conrad was a soldier in Sullivan's Army (1779). He moved his family to New York State (near Ithaca) after Julianna died. He remarried (Catharine ?)and they had another son, Henry. Conrad died around 1809 and is buried near Ithaca, NY.
Thank you for posting the photograph of the headstone. I have never seen it, but have researched my lineage and it mentions that she is buried in the Stillwater, NJ cemetery.
