I am from Germany and I have started to search for my ancestry only recently.
My great-great-grandmother Johanna Czekalla was married with Valentin Jedraszczak. According to the marriage entry of their son Joseph (*1882), who married Viktoria Spasioska (daughter of Matthias Spasioski and Josepha Dombrowska) on 28th June 1906, Johanna and Valentin lived at Gembitz-Gut in 1906.
