I am sorry I misread your post.
From the records of Rev. John W. Weber, German Reformed Church, Westmoreland County, Pa. The first date is the birth, the second the baptism.
Jacob 7/14/1795 10/4/1795 Christian Lauffer/Sara
Magdalena 5/19/1797 6/5/1797 Christian Lauffer/Sara
Sara 5/19/1797 6/5/1797 Christian Lauffer/Sara
Catherina 9/18/1801 11/1/1801 Christian Lauffer/Sara
Maria 9/28/1802 10/21/1802 Christian Lauffer/Sara
Note: baptized at same time mother was buried.
Note: Jacob Hugus and Catherina were the witnesses for the baptism of Catherina.
Aaron 8/28/1806 10/5/1806 Christian Lauffer/Elizabeth
(Note: Aaron Heyart and Margaretta are listed as the grandparents. I believe this is Aaron Teegardin and Margaretta Diebel. Could it be that Teagarden, Degart and Heyart are all variations of Teagarden, as some researchers believe? Maybe the second and third marriages are really only one marriage.)
Sara 3/18/1808 3/28/1808 Christian Lauffer/Elizabeth
Christian 6/2/1810 7/29/1810 Christian Lauffer/Elizabeth
The rest of the children I also have. Henry, Solomon, Ellen,
Sarah, Daniel and Simon Peter. All of the children you have listed are mentioned in the 1838 Pickaway County Partition record of 1838, which states that Daniel Loffer and Simon P. were minors. (The first Sara and Aaron may have died young, therefore not mentioned in the partition record.)
In the History of Howard and Tipton County Indiana, it says "among the early settlers who came in prior to 1844 may be named Christian Loffer and his sons Daniel Loffer and Simon P. Loffer. They moved to this county from Ohio and were identified with the township for a few years, when they sold out and moved to Iowa. I have rambled enough now, let me know what you think.
