Anne Bonny 

She was a lady pirate! She married James Bonny at first but was not happy with him so she sought out to look for some adventure. That's when she found Calico Jack Rackham, a pirate captain with a ship. She joined his crew as a man (she was acting, ofcourse!) and fought under his command. She even managed to persuade the crew for extreme bloodshed and violence. However, she was later captured and sentenced to death, but the death sentence was not carried out as she claimed pregnancy. No one knows what happened to her but it is said that she went back to her husband.
