Sienkiewicz was born on May 5, 1846 in Wola Okrzejska, Poland. His family were impoverished Polish nobles, on his father's side deriving from Tatars who had settled in the Grand Duchy of Lithuania. His parents were Józef Sienkiewicz (1813-1896) and Stefania, née Cieciszowska (1820-1873). He had five siblings: an older brother, Kazimierz (died during January Uprising), and four sisters, Aniela, Helena, Zofia and Maria. His family were entitled to use the Polish Oszyk coat of arms. Wola Okrzejska belonged to the writer's maternal grandmother, Felicjana Cieciszowska. His family moved several times, and young Henryk spent his childhood on family estates in Grabowce Górne, Wężyczyn and Burzec.
