The Book of Esther in the Old Testament tells the story of Queen Esther, the Jewish wife of the king of Persia who saved her people from extermination. There was also one Esther by birth in the Black family – Hester Black.
It's also possible that her name derives from Hesperus, the "Evening Star" from Greek mythology (Vesper for the Romans). This was a name assigned to the planet Venus, visible during the evening, whose morning counterpart ("Morning Star") would become called "Lucifer" in Latin.
