The David Wilber Yoh Family Home Page

I am new at this endeavor. I am trying to trace my roots back to Germany / Austria. Allegedly, there were four brothers who held substantial vineyards around Baden Baden, Germany. The Austrians drove into their farms and confiscated much property and killed some of the family. The brothers shot their way out of the country and had almost nothing left when they reached safety. One brother got as far as Baltimore Md. without a penny, but unharmed. For some mysterious reason, probably not to be traced or have any retribution imposed on the remaining family in Germany, all the brothers changed their names. The original name as far as can be determined is "Von Joh." There supposenly is a "JOH" family in Baltimore -- I plan on getting in touch with them soon.My grandfather and father were raised in Van Wert Ohio. My grandfather's name is "Wilbur Yoh" and my dad's name is Cahrol George Yoh. My dad's brother's name is Merel.
Any information would be greatly appreciated. I am very willing to provide all information I have or will get.
Thanks in Advance
