One of the basic sources of genealogical data for the history of particular gentry entries of baptism, weddings and deaths in church registers. They are often dispersed among register achives of various parishes, what makes it difficult to collect and recognize them. In this article an attempt was made to compile all available register entries from the second half of the 17th and the whole 18th century which refer to a Podlachian family coat of arms Ślepowron, siblings and descendants of Wiktoryn Kuczyński, the castellan of Podlachia. Throuhout the centuries members of this family belonged to the gentry elite of Podlachia. Preliminary research carried out on register certificates of ten parishes located in different dioceses resulted in collecting almost all baptism, wedding and death certificates relating to the generations of Wiktoryn Kuczyński'ssons and grandsons. These certificates allowed to complement in many respects previous knowledge about the genealogy of this line of the Kuczyński family, and thus to specify the dates of particular events and increase the number of family members, especially by including the persons who died in their infancy. All the discovered certificates werw included in full length along with the note on the place of their origin. The data from the certificates was supplemented with information from the 18th century newspapers
