I have been researching my Neugebauer family line for many years and have put much of the information online. I am still getting more names and dates of ancestors from the Kalkau area of Opole which was in Schlesien, Germany but is now in southern Poland. My Neugebauer ancestors settled in North Dakota in 1890. Please get in touch with me at firstname.lastname@example.org if you can add more information to the Neugebauer website. Most of my research is from original church records and has not been otherwise published by anyone else.
