Tekst źródłowy strony Plik:492px-POL COA Wasilewski.svg.png

Most honorable and noble family of Wasilewski Coat of Arms - this family is associated with Ostoja. There is no sources to confirm any association with Ostoja - the only thing associated here is a sword and one moon that is of different color than in Ostoja. On such poor evidence, it is still linked to Ostoja. One have to ask if it is enough to have a sword in the Coa to be automatically associated with Ostoja.
