It was very exciting to see this post regarding George Christian Beilstein. My ggg-grandmother was his half sister. My gg-grandfather George Christian Reisinger was named for his uncle George Christian Beilstein. I spent an entire week last year in Salt Lake City researching German Church records and copied many of the Beilstein listings from Evangelische Kirche Bierberau. George Christian Beilstein's marriage record does have an error. Johann Wendell Beilstein was not his father. He was his grandfather. This is confirmed in all the other family information and George Christian Beilstein's birth record, which I will paste below in German and English. The error was made in the original church book. It looks as if they were going to word it similar to the birth record below, but omitted the father's name continuing to his father instead. I would be most interested in learning more about the descendants of George Christian Beilstein and when and where they migrated to America.
