How to confirm nationality German

The only solution is to go to the archives and search for documents.
The Germans who lived on the territory of the Russianempire, often recorded births, marriages, deaths in Lutheran churches, which were rather small and whose documents were very poorly preserved. Nevertheless, first you need to try to get an excerpt from the metric book of the Lutheran church - this is a direct confirmation of nationality.
If the documents of the Lutheran parish do notpreserved, the German nationality can also be confirmed with the help of metric books of Orthodox churches. If a person was a Lutheran or Greek Catholic, this was recorded in metric records of birth, marriage and death. Especially clearly recorded about the marriage. After the First World War, the Germans who were captured were left in Ukraine, Belorussia, and western regions of Russia. They worked mainly in agriculture and in industrial enterprises. Many of them marriages with local natives - in such cases, the metric record of the marriage or the birth of the child stated: "a subject of the Autotro-Hungarian Empire," which is a confirmation of nationality.
Confirmation of nationality can be found in the most unexpected documents.
For example, in the materials of one of the district committees of the trade union in 1921, a document was found: "Lists of persons of German nationality for registration with the district military commissariat".
Such documentary evidence can also serve as an indirect confirmation of nationality.
If the original search by metricbooks did not lead to success, then it is necessary to study documents at the place of work: track records, alphabetical lists of employees, personal files. By the way, quite often in personal files are kept notarized copies of passports (especially when it comes to documents of the 50s of the last century), and in them nationality was indicated necessarily.
