Christopher Kessler born 1821 is where we start with this surname.  He immigrated from Germany to the United States about 1846.  In January of 1847 he married Anna Maria Assmann, daughter of Mathis Assmann and Elizabeth Schneider.  They had at least 9 children, all of whom I have done a bit of research.  I have no idea for sure who Christopher’s parents are, but I have a lead that his father’s name might be Nikolaus and his mother’s name Petronilla.  (I intend to add more information here with documents, etc.)
