Miłosz was born into a prominent family. On his mother's side, his grandfather was Zygmunt Kunat, a descendant of a Polish family that traced its lineage to the 13th century and owned an estate in Krasnogruda (in present-day Poland). Having studied agriculture in Warsaw, Zygmunt settled in Šeteniai after marrying Miłosz's grandmother, Jozefa, a descendant of the noble Syruć family, which was of Lithuanian origin. One of her ancestors, Szymon Syruć, had been personal secretary to Stanisław I, King of Poland and Grand Duke of Lithuania. Miłosz's paternal grandfather, Artur Miłosz, was also from a noble family and fought in the 1863 January Uprising for Polish independence. Miłosz's grandmother, Stanisława, was a doctor's daughter from Riga, Latvia, and a member of the German/Polish von Mohl family. The Miłosz estate was in Serbiny, a name that Miłosz's biographer Andrzej Franaszek has suggested could indicate Serbian origin; it is possible the Miłosz family originated in Serbia and settled in present-day Lithuania after being expelled from Germany centuries earlier. Miłosz's father was born and educated in Riga. Miłosz's mother was born in Šeteniai and educated in Kraków.
