Holszanski

Olshanski (Lithuanian: Alšėniškiai or Alšėnų kunigaikščiai, Belarusian: Гальшанскі, Polish: Holszański) was a Lithuanian princely family of Hipocentaur coat of arms from the Grand Duchy of Lithuania. Their patrimony was in Halshany (now in Belarus) and their property included Rokantiškės and Halshany Castles. During the 14–16th centuries most of the family was Orthodox by faith and Ruthenian by language, although there were exceptions, in particular Paweł Holszański was a Catholic Church official.

The family was founded by Ivan Olshanski (fl. 1382–1402), a close ally of Vytautas, Grand Duke of Lithuania. Ivan's daughter Uliana married Vytautas while granddaughter Sophia of Halshany married Vytautas' cousin Jogaila, King of Poland. Sophia gave birth to Jogaila's sons and became the mother of the Jagiellonian dynasty which ruled Poland, Lithuania, Hungary and Bohemia. The male line of the Olshanski family ended in 1556 with the death of Prince Semen (Paweł Holszański, last-but-one male representative of the family, died just one year before). Princess Maria Olshanskaya, the wife of Andrey Kurbsky, died in 1586. Their estates were inherited by the Sapieha family, which hailed from Smolensk.
