Thanks Tilman for your reply. Yes we are directly related to the Austrian Count Harrach family. Someone once told my father that we were not from the royal Harrach family ANYMORE. We were told that we didn't belong to the royal family because Johann Karl married a non royal, thus he lost his title of count. But after researching that, a count doesn't loose a title because of marrying a non royal. So I really want to know if we are all counts and countesses (our American branch of the Harrach family). The problem is that no one can find records of the birth of Peter, Count Johann Karl's son. Count Johann Karl (and his brother Maximilian) was supposed to have been killed when he was fairly young in the 30 years war, and had no children. His father was the famous Count Karl I who had many children,(he was related to Otto Friedrich). One of his daughters (she would be Johann Karl's sister) went on to be the only heir of the Austrian branch of the family. And our family was forgotten.
So that is why I'm looking for information as to how to find birth or death records (or any kind of records) in Breslau, where I think most of them were born or died.
