Has anyone heard of the name ZIERLEIN, VON ZIERLEIN ? There is an important reference to a young man of that name who was the assistant of a Duke Paul Wilhelm of Wuerttemberg in 1851. No first name is given, but he was said to have been from Sachsen/Saxony. He disappeared into the prairies and was never heard of again. Any hints from America? Any hints from Germany where this family comes from? hans.
