Thanks for the data.I'm inclned to think, however, that you have the wrong Peter Achenbach. (There were entirely too many!).
I went back over my notes this morning (while waiting for the snow plow to arrive here in MD) and came upon some earlier material from a Mrs. Janice Kulka.There's a Peter Achenbach (1794-1858) in her family tree as well.That one married Maria Lennart and moved to Wayne Co. IN, where the last four of their children were born.The father of that Peter Achenbach was also named Peter (1769-1844), married Catherine ??? and lived in Lebanon Co. PA.
If you have any interest in this branch, I can send you the file (once I've reconstructed it from some elderly Family Group Sheets).
