The Kurnatowski was a noble family within Poland and the Polish-Lithuanian Commonwealth from the 14th century into the 20th. The family was part of the Łodzia clan and were participants in politics, arts, military endeavours, and Calvinist clergymen. As magnates and members of the nobility, the Kurnatowskis had extensive land holdings which were all confiscated during World War II and especially during the Soviet occupation of Poland from 1939 to 1990.
The title of count (hrabia in Polish) was bestowed by Papal edict in 1902 to one of the branches of the family. Another line allegedly received the title of "count" in 1916 from the Tsar Nicholas II. Some of the Kurnatowskis were ardent members of the Polish Reformed Church, or Calvinists, producing a number of clergymen, although the Duisina and other family lines have remained Roman Catholic since at least the 13th century.
