Hi Tom,
your Mary Gertrude Schaupman could have come from Bad Laer near Osnabrueck. This is the place of origin of the Schaupmann family in Germany. So you can try to get help about the page www.amerikanetz.de.
I work on the page www.auswanderer-oldenburg.de. I would be proud to present informations abot your ancestor. Could you give me your datas about the cildren of Joseph and Mary Gertrude?
Best regards,
Gunter (Juechter)
