I am not from the Ernest family but on findagrave at Salem Stone Church Cemetery in Carlisle Cumberland County PA I found a Conrad Ernest b.Dec. 12, 1797 Cumberland County PA
d.May 5, 1847 Cumberland County PA. Wife Elizabeth and son George also buried there. From there, can find others. He was of German descent as was my grandfather Coryea who was probably a Hessian. They both lived in North Middleton nearby. Conrad Ernst is mentioned as witnessing our family events. Wonder if he too was Hessian but have NO NO NO proof at all that he was! Cool photo of Conrad on findagrave. Let me know if I can help further.
