Until a few weeks ago, I thought all the Hasselbachers of Gresten participated the Counter-Reformation Exodus from Austria to the Aischgrund of Mittelfranconia. Of course we always knew that at least one Hasselbacher in the Aischgrund (Valley of the River Aisch) came from villages nearby Gresten, but until this summer it was not possible to attempt any family connections to modern Haselbachers living elsewhere in Austria.
During an additional study of Gresten church books from the 18th century I found at least one Haselbacher who remained in Gresten. His name was Adam and I present his history in the Hasselbacher Family Website.
