Our origins are located in the Niewino villages, near Bielsk Podlaski (Podlasie) in the 15th century. According to local historians and 19th century genealogists, the Książyk are members from the Niwiński family, a branch of the Paprzyca knights who settled in the area of Wyszki. The Paprzyca are a prominent family from the Kuszaba Clan. Along with other Paprzyca relatives, the Książyk were allowed to use the coat-of-arms of the clan. From our researches, the first recorded Książyk was Andrzej, Chamberlain of King Alexander Jagello from 1503 to 1505. In 1569, Stanisław Książyk swore allegiance to the Polish King Sygmunt August II.
Later, Książyk people settled near Poznan in the area of Śrem, near Kalisz. In 1752, one of them was granted the privileges (przywilej na sołectwo) over the village of Turek. Today, the largest group of Książyk families (about 74 people) is still living in this same area of the Greater Poland Province (Wielkopolskie).
