Yes! I read that “Hadassah,” is Hebrew for Myrtle, but I don’t know that to be fact.

According to Esther 2:7, Esther was originally named Hadassah. Hadassah means “myrtle” in Hebrew. It has been conjectured that the name Esther is derived from a reconstructed Median word astra meaning myrtle.[4]
This is true ... the "myrtle" being a highly regarded flowering tree, not "that weird name of my great-aunt." Non-canonical sources say that Hadassah was the Hebrew name of the Jewish heroine Queen Esther. "Esther" is a Persian name, a variant of "Ishtar."
Ah... already covered... oh well... late to the thread.
It is Queen Esther’s other name. If you check back, Sarah loves the story of Esther, and has used the phrase “for such a time as this”, I think. Also when Andrea Mitchell was stalking her clear to the fishing boat after she resigned, she said, “well, politically speaking, if I die- I die.” She also has mentioned telling Piper the story of Esther.
