"Cio\u0142ek (Polish for \"bull calf\") is a Polish coat of arms, one of the oldest in medieval Poland. It was used by many szlachta (noble) families under the late Piast Dynasty, under the Polish-Lithuanian Commonwealth, during the Partitions of Poland, and in the 20th century. The variant names \"Siolek\" and \"Cialek\" arose from miscommunication among early-20th-century Polish immigrants to the United States."@en . . .
