Wenceslaus I of Bohemia
The first factual mention of an ancestor of this clan dates back to 1237, during the reign of the Přemyslid king Wenceslaus I of Bohemia. Over the next three centuries they were only minor nobles with estates in northwestern Bohemia, around the village of Vchynice () near Litoměřice. Holding of Vchynice manor was confirmed by the Habsburg emperor Rudolf II in 1596 and in 1611 one of the family's members, Radslav Vchynský of Vchynice the Elder, ennobled as lord (), became a member of the Diet of Bohemia ("zemský sněm").
