Astrauskienė is a Lithuanian surname, the feminine form of Astrauskas, specifically used by married women. This surname is rooted in Polish toponymic origins, reflecting the historical ties between Lithuania and Poland. Etymology The base surname Astrauskas is a Lithuanian adaptation of the Polish surname Ostrowski, which derives from Polish ostrów meaning "river island". Originally, Ostrowski indicated a person from a place named Ostrów or Ostrow, common settlements located on river islands in Poland. As Lithuanian adopted the name, it was suffixed with -as to fit masculine grammatical forms, while Astrauskienė is formed with the feminine suffix -ienė, marking marital status. Historical and Cultural Context Lithuanian naming conventions traditionally assign distinct feminine suffixes for married and unmarried women. The surname Astrauskienė thus identifies a married woman bearing her husband’s or father’s lineage. This pattern contrasts with the variant Astrauskaitė, which denotes an unmarried female descendant. The Polish original Ostrowska serves the same purpose among Polish bearers, reflecting shared name-formation practices across Baltic and Slavic cultures. The forebears data indicates the surname is recorded in Lithuania, consistent with its most common usage. Meaning: “(married woman of) one from a river island” Origin: Polish topographic surname, adapted into Lithuanian Type: Feminine form of Astrauskas, patronymic locative Usage: Lithuania, especially among married women
