I recently requested a search of Welke records in the Radom, Poland Archives. I received 70 documents, dates: 1830-1907. I did not see any positive connections to any of the Welke dates mentioned in this thread. Some of the other surnames, spouse and parents, associated with these births, deaths and marriage: Bluemke, Fechner, Stojke, Kriger, Ryk, Ruzowska, Nikel, Funk, Kruger, Radke, Kuhn, Grams, Schonknecht. If any of your Welkes are connected to any of these names, you may leave me a message here and I will get back to you, although it may take some time, which I apologize for in advance.
