Bunderman cites the evidence of Rev. Alexander Decker, through a Philadelphia genealogist, William H. Mervine, that Johannes married a Christina Hahnin (aus Bechlob) on April 7, 1760. Mervine researched the records at the Lutheran seminary at Mt. Airy, Pennsylvania, a repository for Lutheran records from the area. The church in question was probably St. Michael's Lutheran Church in Germantown, Philadelphia, which served as the only Lutheran church in the vicinity for German immigrants. Unfortunately, the pages in the register for 1760 have become illegibly faded and the entry for Johannes' marriage can no longer be seen. Only expensive technology can, perhaps, restore what has been lost.
