Did Esther Nehemiah and Daniel live at the same time?

Daniel probably died shortly after Darius took the throne in 521 BC (he would have already been well over 90 years old at this point). The book of Nehemiah begins in 444 BC, so they probably missed each other by at least 50 years. Esther was a teenager in 482 BC, so Daniel had likely been dead for about 25 years at this point. Esther would have been in her early to mid 60's when the book of Nehemiah began, although her husband, King Xerxes was assassinated 20 years earlier (he was probably bout 20-25 years older than her (do the math a 37 year old king marrying a 14 year old or so, Esther...yuck...that's not what they showed in the movie). Anyway, there's no record of whether Esther was assassinated with her husband (which was likely), or if she was assumed in to the next King's harem (also possible...although a Persian King would have probably not been interested in a 35 year old, non-virgin wife. We just don't know.

So, we know that Daniel was dead long before Esther was born and I'm going to guess that Esther probably died with her husband in 464 BC. Since Nehemiah was a leading figure in Jerusalem by 432 BC, I'm going to guess that he was born before 464 BC, so yes they probably lived at the same time. Nehemiah probably knew of Queen Esther before she died (I'm guessing she died in 464 BC) and maybe even met her a few times when He was a young boy. That being said, Esther probably didn't live to see the events of the book of Nehemiah, unless she survived the assassination, in which case she and Nehemiah may have known each other personally. I'm also guessing that Nehemiah was probably not around when the events of Esther took place or at the very least was too young to remember them clearly.
