I too, and looking for information regarding my family. My great grandfather would likely have known Rudolph George Reinke as he was born there in May 30, 1864. His name was Wilhelm Ferdinand Zieroth and I had been having difficulty in determining where this town was since 2 world wars have blurred borders and changed the names. I had misspelled Krupotschin as Krupulschin and nothing was coming up until I managed to get hold of the family Bible and got it right.
What other info have you discovered about the town?
