You can read my message to Joe. There I explained how they got to Krajina (in 1500's, I presume). You did quite a research yourself. There are four villages in ex-YU that have the name Babici. One of them is in Bosnia, 2 in Croatia, and one in Serbia, I think. Somewhere in my home town I have this map of migrations due to the Turkish invasion. I'll try to find it. That might help you some. I doubt that there could be some record remaining in Krajina. The Church had all the records about ppl, but, since many of the Serbian Orthodox Churches were burnt by the Ustashe in WWII and most of the remaining ones in the recent war(s), there could hardly be any precise record about that period. You know, the Church was the only Serbian institution that survived the Turkish rule. If there were some records about how the Babic's got to Krajina, it could only be found in those churches (if there are any remaining). Correct me if I'm wrong, but I think that your ancestors were Orthodox. They lived in Babici, Bosnia, (the village is near Tuzla, right?) which was under the Turkish rule. In 1850 Serbia was the only Orthodox christian independent country in a 1000 miles radius. So they moved to the nearest Serbian city - Sabac. Like my folx. They did move for just about 20 miles northwards (from the village of Ploce to Trstenik, central Serbia), but I think they only cared about crossing the border to the free territory - in those times Serbia was 1/4 of today's size. Many Serbs moved from surrounding areas to the Motherland. The migration to Belgrade was typical for Sabac inhabitants in the early 20th century.
Alas, my problem is this. I'm looking for my great-grandfather's brother - Dobrivoje Babic. He was a Yugoslavian Royal Army sergeant, but, since the comms conquered Yugoslavia in the end of WWII, he fled westwards. Some say he was killed during the crossing of Drina river. I doubt it. Since he was an intelligence officier, the other version is more likely. He escaped and went to West Germany. Some say they had seen him there. I think he didn't want to make problems to his family which was under Tito's regime. I know that my chances to find him are 1:1 000 000, but... I'm sick and tired of looking at my old family photo's from the 30's and the 40's, all yellow, with one side torn off, a side where a man stood (his arm often remained in the remaining of the picture) with an excuse: "Hush, don't anyone hear you, he was a chetnik, they might arrest us." Eventualy I got arrested by Milosevic's police, but that is of no importance. I just wanted you ppl to know that I wish that if anyone of you ever hears something about Dobrivoje, pls cntct me. Thx
