In old Polish there was also a special form of name for unmarried women, so for example: Jan Kowalski has a daughter, Anna Kowalska. When she is young, she is called Anna Kowalszczonka, Kowaliczka or Kowalówna depending on who you asked (and you can't reliably reverse these forms into the original name) When she is grown up, she is called Anna Kowalska. As it happens, the country was part of the Russian empire, so she's also called Анна Ковалска or Aнна Kовалская, depending on who you asked. When she marries Jan Kowal, she is called Anna Kowalowa or Anna Kowal. When Jan Kowal dies and she marries Wawrzyniec Słowacki, she is called Anna Słowacka. But her husband is from Austria-Hungary, so he's also called Laurentius Slowacki somewhere in his documents, even though he never uses this name for anything. Their son Stefan moves to Lithuania, but even though he's ethnically Polish, Lithuanian government requires him to have "Steponas Slovackis" printed on his documents.
