You can only expect to find archive material relating to your genealogy if your ancestors worked in the Foreign Service or, as a German national, had direct or indirect contact with the Foreign Office or the relevant mission abroad due to a stay in another country.
Please be aware that the records do not contain civil status records, it is not possible for the Archive to carry out in-depth genealogical research, and personal records (e.g. personnel files) can only be accessed 30 years after the death or 110 years after the birth of the person in question.
Biographies of persons who served in the higher service prior to 1945 can be found in the “Biographisches Handbuch des deutschen Auswärtigen Dienstes” [Biographical Handbook on the German Foreign Service].
Personal papers are held in the Federal Archives’ central database of personal papers.
