170 Łukasz Bielecki, Maciej Głowiak In the initial phase of the project, only the area of the Grand Duchy of Poznań (under Prussian occupation) was covered. Later, the scope of the project extended and included the part of Greater Poland which in the 19th century was under the Russian occupation (the following districts: Słupca, Konin, Koło, Kalisz, Turek), other regions that have historically been associated with Greater Poland (Wałcz, Złotów), as well as the bordering areas (Tuchola, Radziejów, Sieradzkie). It was possible to catalog the majority of marriage certificates entered in the 19th-century books and registers of the registry offices from these areas. These certificates were entered into a database, which was made available online in February, 2006. Since then, tens of thousands of people from Poland and abroad managed to find information about the location of their ancestors’ marriage certificates. Many genealogy specialists (mainly ancestors of the emigrants from the Poznań Duchy) managed to establish the origination of the people they were interested in, owing to the data found in the Poznań Project database.
