Goneril

Goneril is a character in William Shakespeare's tragic play King Lear (1605). She is the eldest of King Lear's three daughters. Along with her sister Regan, Goneril is considered a villain, obsessed with power and overthrowing her elderly father as ruler of the kingdom of Britain.

Shakespeare based the character on Gonorilla, a personage described by Geoffrey of Monmouth in his pseudo-historical chronicle Historia regum Britanniae as the eldest of the British king Lear's three daughters, alongside Regan and Cordeilla and the mother of Marganus.
