I know one Perz family but they are from Kraków area.
My gr-grandfather name was John Perz, he had two brothers ,James and Lawrence (I'm sure these names are Americanized).
Look for Jan, Jerzy and Wawrzyniec
They left Poland around 1885.
There was no Poland in 1885. They were from Prussia probably.
