AGOFF South East Europe is a center that includes an area of Hungary, Romania, and Yugoslavia genealogy research for Arbeitsgemeinschaft Ostdeutscher Familienforscher, an East German Genealogy Society with research centers throughout Eastern Europe.
There doesn’t appear to be much online yet, for the AGOFF South East Europe area, but here are links to their site:
“The Germans in South-Eastern Europe consist of very diverse and disparate parts: The border lands in Slovenia and the West Yarn, the larger Volksinseln with its own institutions, as well as the ruins of a few villages or even courts; As well as peasant colonists; Since the high Middle Ages, long particularly privileged groups such as in Siebenbürgen or the Spiens, but also immigrants of the 19th century as in the Dobrudscha, Bessarabien or Bosnia.”
“The largest group, the descendants of German immigrants of the eighteenth century, who had been designated as Donauschwaben since the end of the First World War, has its own research center. The other groups are grouped together in the Research Center South-East Europe, which is divided into three research areas: the Research Area of Yugoslavia, the Research Area of Old Hungary and the Research Area of Romania.”
