ENThe progenitor of the Woyniłłowiczes’ from Boryszyn ancestral line was Stefan, a son of Iwan Woyniłłowicz. In 1653, one of his three sons, Trojan, bought Boryszyn, which gave the name of this family line. Trojan was a wealthy man – except Boryszyn, he came into possession of much of the part of Niańków (by buying his brothers’ heritage from them), as well as Sieliszcze and Łukonica. Boryszyn was inherited by his son, Jan Teodor. Then, it became part of the inheritance of his grandson, Józef, and a great-grandson, Florian, who suc-ceeded Trojan as the head of the Woyniłłowiczes’ from Boryszyn ancestry line.
