Eine im Aufbau befindliche Datenbank der Familie Olschinski aus Ostpreußen sowie verwandter Namensformen wie Olschinsky, Olszinski, Olshinsky, Olszynski, Olszynska, Olczynska.
Die Datenbank enthält zur Zeit circa 350 Personen. Die ältesten bisher bekannten Erwähnungen in Ostpreußen beziehen sich ab 1708 auf den in Groß Bössau im Kreis Rößel lebenden Bauer Peter Olschinski und seine Nachfahren. In den Jahren bis nach 1800 wurde dabei die Namensform Olszynski und Olschinski für teilweise dieselbe Person benutzt.

On September 29, 1939, Poland was divided between Germany and the Soviet Union as a result of an agreement signed by the German Foreign Minister Ribbentrop and the Soviet Premier Molotov. This called for Poland to be divided approximately along the Warthe River. One of the terms of this agreement was that German ethnics were to be relocated from the Russian area to the German area. As this was being done, all those who claimed German ethnicity were interviewed and given travel papers. These resettlement records are stored at the Berlin Document Center and are available on microfilm at the Family History Centers of the LDS church. Each film contains several thousand entries, giving the primary individual and his or her immediate family. If the record is for a married male, it will give the name of the wife and her family as well. If the record is for a married female, it usually does not give the name of her spouse, but will often contain the names of any minor children. The data include date and place of birth, occupation, parents place of birth and sometimes the date of birth, where the parents may have died and the date and place of marriage.
