Your message was posted quite a while ago. I just started this quest on tracing ancestors about a year ago. Until last year I had no information beyond my great grandfather, who was William C. Echard. His father was Jacob Echard born 1818, married to Nancy Rhinehart. Jacob's father was Christian Echard, born in 1781, married to Christina Hoffheintz, born in 1791. I got all of this over the internet, so I assume it is correct. So, the Christian you mention must be my great-great-great grandfather. You may have found this information in the years since your message was posted. If you have information that what I found is correct, please let me know. Thanks,
(P.S.) I was born in Fayette County, PA and now live in N.C., after living most of my adult life in Ohio.
