Ricardo. Sorry, I forgot to tell you more about the OSB (Ortssippenbuch). In this case the RC Church records are microfilmed and stored in the Government Archives and also at the LDS in Salt Lake City. The book(s) contain information such as, births; baptism and deaths. Only since the existence of the church but not the village. Most of the villages in Banat have their own "HOG" (Heimat Organizion Gemeinde) or translated into English; Homeland Community Organisation. These books only came in existence after about 5-10 years ago. In order to obtain the microfilms from the Government Archive, the costs were outrageous. Some villages could not effort the cost for the microfilms and the printing and are unable to publish an OSB. Many volunteered hours are put into a book. People from their own community would volunteer for days. In the 1700-1800, the church records were written in Latin, after in Hungarian and then in the old German Script. It became a hard task to abstract the microfilms.
The Germans from Russia, Ukraine, Bessarabia, Crimea, etc. To my knowledge, have not yet installed such system, as the Banater-Donauschwaben. They have some "Heimatbuch" (Homeland book), which does not contain such particular data as the OSB. It pertains more history of a village and has some data.
I'm not familiar with the Orthodox Church; I'm sure their church records are microfilmed. I haven't been involved with the Orthodox Church recently but I know there are plenty history books. On our holidays this summer, we travelled through Central and North Eastern part of Alberta. I couldn't believe how many, Ukrainian, Polish and Romanian people from Bucovina have settled there. Their books covered more of the early pioneer settlers in Canada. It really was interesting and enjoyed it.
