Today I discovered another country that includes the birthplace of one of our ancestors. Apatin, Bacs-Bodrog, the birthplace of 2nd-great grandmother Julianna Vill in 1836, is now 30km south of the Hungarian border in Serbia. Prior to the 1920 Treaty of Trianon Apatin was in the Hungarian county (megye) of Bacs Bodrog.
Looks like a lovely area on the Danube.
There is a website created by fellow genealogists that includes pictures, village map and a registry of Apatin descendants. And the website is in English!
