I have a U.S. church confirmation record that gives a place of birth as :Heinrichhau, West Preussen". About the only Internet reference to "Heinrichha" I found says "Heinrichhau/Kr. Frankenstein". There was not Kr. Frankenstein in WP, but there was one in Schlesien. Was there a Heinrichhau in Kr. Frankenstein in Schlesien?

Hi, yes Heinrichhau is in Schlesien(Silesia), specifically Nieder Schlesien(Lower Silesia). Kreis Frankenstein means the village/town nelonged to the juristiction of the larger city called Frankenstein. What are the surnames you are researching?

False alarm. I have concluded the reference should have been to Heinrichau (one "h"), in Kr. Rosenberg, Westpreussen.
