Anne Chamberlyne

Anne Chamberlyne was a female tar who, in 1690, joined the crew of the Griffin Fireship, a ship commanded by her brother, Clifford. In June of 1690, she fought the French at Beachy Head. As noted by Ishida, "Although most women marines came from the lower classes, she came from the nobility."
A plaque in her memory at All Saints Church, Cheyne Walk in London used to exist, but it was destroyed in World War II during a bombing raid.
The plaque stated:
She is the first known female tar in British history.
She was the daughter of Edward Chamberlayne, and sister of John Chamberlayne.
