Also don’t forget Anna Komnene. She was the oldest daughter of Alexios I (who unwittingly kicked off the Crusades). After unsuccessfully trying to overthrow her younger brother, she was exiled to a monastery where she ended up writing the Alexiad which provides much of our information about the early crusades including first hand descriptions of some of the key players as well as as weapons and tactics.
