While in Salt Lake City at the National Genealogical Society’s Family History Conference last week, I seized the opportunity to conduct some research in the Family History Library. My primary research objective was to identify the administrative divisions for parishes in the area north of Warsaw where my Burski, Chodkowski, Czarzasty, Kamiński, Klonowski, Krzyczkowski, Milewski, Mossakowski, Niedziałkowski, Rembowski, Skierbowski, Smoleński, Ślaski, and Zaboklicki ancestors lived.

Because the borders of Poland changed so often throughout history, genealogists may find that correctly identifying the name of the places where vital events in the lives of their ancestors occurred may be a difficult task if they attempt to enter the names of the places as they were known at the time of the events.
