If you can't find any German connections, there were old Yunker families that migrated to Russia during the Potato famine and then in the 1870-1890 timefram
migrated from the Volga Region, near Obermunjor Russia to the United States. Give this a try if you run into a dead end in the Germany area. Speaking of
Germany be careful when looking for "Germans" before 1890 as Germany didn't even exist before that time. Many people were refered to by the region in which
they lived. Hope this helps. Happy Hunting!!
