Yes, your John Tschopp and Madeline Stohle (my spelling Stohler) are the parents of my husband's line of John Jacob Tschopp, Sr. born Dec 05, 1767 at Lebanon Co., Schaefferstown, PA.John Jacob Tschopp did live inNorthumberland Co., PA. So-your Elizabeth and our John Jacob are siblings. Can you give me any dates on:Catharine Tschopp who married John Zerbe, like birth dates, etc.I do not have a John Zerbe that married a Catharine Tschopp in my file.I have a John Zerbe married a Margaret Dick.Love to know how this Catharine is connected to the family. Your Elizabeth Tschopp was born Oct. 7, 1789 in PA--do you know where? Abraham Troutman was born Dec 09, 1773--do you know where? Do you have the marriage records.I figure it must have been ca. 1801.
