Esther

According to the Bible (Esther 2:7), she was orphaned and either adopted or fostered (scholars are unclear about how to interpret the text) by her uncle (or cousin), Mordecai.

She is famous in Jewish history as the queen (she was the wife of King Ahashueros) who saved the Jews from the genocidal plot of Haman, whose downfall in 356 BCE is celebrated during the Purim festival.
