Ślepowron coat of arms

Ślepowron is a Polish coat of arms. It was used by several szlachta families in the times of the Polish–Lithuanian Commonwealth. From the fifteenth century, the descendants of the Ślepowron family began to use names taken from their lands. This led to many different surnames being created within one family, symbolically united under the Korwin (raven) coat of arms, which is thus unique in Polish heraldry. Wawrzęta Korwin de Ślepowron is the oldest known ancestor of the family, although their oral traditions claim descent from Marcus Valerius Corvus, a Roman general.
