I still haven't found a connection between my Bohemian Zipperer's that immigrated to Brazil and the ones who immigrated to USA. However, I found some interesting informations in a old book:

In the region of Flecken, Bohemia (now Fleky, Czech Republic), there were in 1654 three farmers Zipperer: Andreas Zipperer, Wolf Zipperer and Hans Zipperer. In 1713 there were four: Hans, Hans, Adam and Georg Zipperer. It's not mentioned how they were relationed.

I'm descendant of this Georg, but I can't know who was his father. Georg had Peter Zipperer, who had another Peter, who had Jakob Zipperer, Josef Zipperer, and Georg Zipperer..

if some of these names are common to someone's researches, please let me know..
