The House of Piłsudski (Lithuanian: Pilsudskis, Pilsūdiškiai) is a family of nobility that originated in the Grand Duchy of Lithuania and whose notability increased under the Polish–Lithuanian Commonwealth and the Second Polish Republic.
[9] A notable member of the family is Roch Mikołaj Piłsudski (c.1680 – early 18th century), Pantler of the Duchy of Samogitia.
[10] His marriage to Małgorzata Pancerzyńska—whose brother, Karol Pancerzyński, was Bishop of Vilnius—raised the wealth and prestige of the Piłsudski family.
The last remaining male member of Józef Piłsudski's family, Kazuyasu Kimura, died on 17 December 2022 at the age of 70.
[11][12][13] He was a grandson of Bronisław Piłsudski, Józef's older brother who married an Ainu woman and lived in Sakhalin.
