Hi Lisa, I have quite a bit of information now on my Viol ancestors. They came from Thuringen. I did not see the names you mentioned in my family tree. If this helps at all, the closest match for that time period was named Johann Gottfried Hermann Viol from Gunstedt, Thuringen b. 1835 m. 1858 Waltersdorf to Johanna Maria Lange.
Good luck to you on your search.
Best regards,
Lisa Viol Longoria
