The following article is a direct translation from the classic Genealogical and Heraldic reference "Herbarz Polski" by Kasper Niesiecki S.J., (Lipsk) edition 1839-46.
All agree that this coat of arms was acquired in Poland in 1332 during the reign of Wladyslaw Lokietek. The King led an expedition against the Knights of the Cross. When the army reached the enemy's camp, a knight of the house Jastrzebiec concealed flaming arrows from the night watch with which he succeeded in torching the enemy's tents. The fire enabled the King's army to rout and kill the enemy with dispatch. The Knight's ingenuity was rewarded with the addition of an arrow to the family's coat of arms which was then named for the village, BIALYNIA, near which the action took place.
Other families using BIALYNIA are: Mirski, Rzepecki, Wilczek, Zablocki.
