The House of Dziaà Âyà Âski was a Polish noble family whose name comes from their original place of settlement, Dziaà Âyà  in Dobrzyà  Land. Members of the family held the tile of Count and used the Ogoà Âczyk coat of arms.
The original head of the family was Piotr from Dziaà Âyà  (died 1441). During the 16th century the members of the Dziaà Âyà Âski family began moving from Kujawy into Royal Prussia. Their connections with the court of the King of Poland allowed them to quickly acquire senatorial positions in the Prussian Diet on the Prussian side of the family (the family had sixteen Prussian senators between the 15th and 18th centuries). In the second half of the 17th century some members began moving to Wielkopolska and over time this became the dominant line of the family. The last male member of the family, Count Jan Kanty Dziaà Âyà Âski died in 1880.
