Jerzy Danilewicz was professor in moral-theology and also confessor to prince Zygmunt Karol Radziwiłł.

### In coalition with Pac family

The Pac family rose into the power of controlling Belarus and Lithuania after the war between the Commonwealth and Sweden, then, at the same time, the Cossack war and also the war with Russia and when the Catholic and Protestant movements in Europe struggled for the power. The time was the middle of the 17th century when Pac and Danielewicz families stood strong behind the King and did not support the Radziwiłł family. After those wars, on behalf of the King of Poland and Grand Duke of Lithuania, John II Casimir Vasa, the Pac family could rule Grand Duchy of Lithuania together with their closest allies like Danielewicz.
In 1653 the property of Bohdanow named after Prince Bohdan Pawłowicz Sapieha in Belarus were passed to Barbara, daughter of Prince Karzimierz Sapieha. Barbara's daughter Tekla Wollowicz then married Piotr Michał Pac and the property passed to the Pac family. Since Piotr Michał Pac had no children of his own, he adopted Michał Danielewicz,(Starosta of Plotelsk, Inspector of the Hungarian border) into the Pac family as he was the son of his sister Katarzyna Pac. As result of that, large property of Bohdanow, the town of Kartena and other properties was passed from the Pac family to Danielewicz.
Ostoja Danielewicz family owned several big properties in Lithuania, Prussia, Belarus and Volyn, Ukraine and held high ranking offices in the Polish-Lithuanian Commonwealth, mostly in the Grand Duchy of Lithuania. Through the centuries Danielewicz was highly respected for and their knowledge in jurisdiction and therefore was often granted the position of Starosta (Lord of Regality) or County Judge as they also many times represented their districts and provinces at the Sejm, the Parliament of the Commonwealth. Danielewicz raised in great power and wealth during the time when the Pac family was in the control of the Grand Duchy of Lithuania.

### During the partitions

The dominance of the Pac family ended because of a lack of heirs and their position was overtaken by the Sapieha family. In the middle of the 19th century the last of the Pac family, Ludwik Michał Pac lost all great properties as they were confiscated by the Russian side for his involvement in November Uprising and his participation in Napoleonic wars against the Russian side. Since the Pac family become extinct, descendants of the line of the Michał Danielewicz are the only ones to continue the heritage of the Pac due to adoption of him and his descendants.
During the Partitions of Poland or Partitions of the Polish–Lithuanian Commonwealth 1772–1918, Danielewicz's of Ostoja participated in many upraising actions witch cause Russian side to confiscate most of the family properties. As the family did not support foreign forces in the Commonwealth and was in opposition, no offices were given to the family anymore. In the end of 18th century part of the family moved to Prussia where they joined Prussian army as officers in hope to fight Russian side that was holding control of the east part of the Commonwealth. After the Napoleonic wars, Marcin Danielewicz received the Order of the White Eagle for his efforts in the fight for the independence of the Commonwealth and Wincenty Danilewicz received French Order of Legion of Honour. Jan Danielewicz died on the fields of Olszynka Grochowska in November Uprising, Piotr Danielewicz participated in 1863 Upraising in Vilnius (the January Uprising) and after the uprising failed was sent to Siberia from where he never came back.
At the end of the 19th century, the family was divided into three lines; the Prussian, Lithuanian-Belarus and Volhynia line. Of over 26 male lines recorded very few survived and the Volhynia line of Ostoja-Danielewicz was excluded from Russian nobility ranks after taking part in uprisings and anti-Russian activities. The main line of the family that sold all major properties including Bohdanow and moved to Prussia.
