If you are new to this area of research, the very first thing you will discover is that the term “Galicia” is used for two very different areas of Europe. When you search for Galicia, ustedes no quieren la región de España! In other words, we are not talking about the region in the northwest of Spain!
Here is the brief description as found on Wikipedia: “Galicia or Halizia (Ukrainian: Галичина (Halychyna), Polish: Galicja, Romanian: Galitia/Halici, German: Galizien; Russian: Галиция (Galitsyia)/Russian: Галичина (Galichina), Czech: Halič, Slovak: Halič, Yiddish: גאליציע (Galitsie), Hungarian: Kaliz/Gácsország/Halics) is an historical region in Central Europe that presently straddles the border between Poland and Ukraine. The area, which is named after the medieval city of Halych, was first mentioned in Hungarian historic chronicles in the year 1206 as Galiciæ. In the 18th century the Galician region was enlarged with territories now found within the modern Polish provinces of Małopolskie Voivodeship and Podkarpackie Voivodeship.”
There are some beautiful historic maps of the area, many of which can be found on the Polish Genealogy Project page. My personal favorites are the Austro-Hungarian Empire 1:200,000 Topographic Maps. Go to the index map and click on a dotted town to see the incredible detail offered in these maps. Very few small villages are not on these maps. This was one of the first maps I saw that showed Bialykamien (on the Brodi section), but I found it in an actual atlas at the Minneapolis Minnesota public library years ago. How wonderful that so many beautiful maps are now online! Maps and gazetteers are your friends!
