I don't know if you are aware that your Christoph Friedrich Schneck line was included in my (co-compiler) book "Im Schneckengang (At a snail's pace)", thanks to information supplied to my co-compiler by some descendants in Indiana. You are included in the lineage. After publication of our book, we had other information on a collateral line from a descendant in New Jersey. I researched the Latter Day Saints microfilm of Kirchenbuch baptisms (MF #1056781,written in German script) for the village of Ossweil, just east of Ludwigsburg. Joh.Michael was born 15-Jul-1758 and married Anna Maria Eckhardt/Eckert.

Christina Frederica b. 7-Sep-1791, died young?; 4th son Johan Jacob b. 16-Oct-1794, married and had children.
