Reitermann, do you know or can you look up Harrach family tree information?
My great grandfather was George Harrach born in 1856 in Breslau, he had a brother named Peter-they both moved to the USA when young men. Their father's name was also Peter Harrach, born in Europe, somewhere.
When my ancestors left Europe and moved to the USA they brought some Harrach things like the coat of arms and a family tree that was written on a scroll with them.
Someone told my father about our ancestor fighting in the 30yrs war. We are not Jewish at all, but direct decendants of the Harrach family. My father's cousin (a USA government agent) researched our family and later went to Rohrau Austria (a few times) and met with our family there-but he passed away and his information is lost. The Rohrau Harrachs welcomed him and no one ever thought we were Jewish.
How do you know that Johann Karl was never married?? Were you able to look up that information?
