What happened to queen esther after xerxes died

I had some troubling questions about how the biblical book of Esther fits with secular history, and so I spent a few hours researching this in the public library as well as online, and gleaned a wealth of information, which strengthened my confidence in the inerrancy of the Bible. I would like to share some of these discoveries, in case there is anyone else who would like more information on the historicity of Queen Esther.

The Problems

There is no mention of Esther at all in secular history (Herodotus is our primary, if not only source), even though according to the Biblical record, she was Queen for at least 6 years. The only Queen of Xerxes mentioned by Herodotus is Amestris, and she is not Jewish so she cannot be identified with the Biblical Esther. This queen is recorded to have had at least 6 children, and had considerable power when Xerxes son Ataxerxes I took over the throne after Xerxes. To add to the confusion, there are writings about Vashti and Esther in Jewish tradi 5 Things About Esther That Nobody Talks About!
