The title Baron Audley was created in 1313 by writ in the Peerage of England. The eleventh baron was created Earl of Castlehaven. The second earl was attainted of felony and executed, forfeiting the barony, but not the (Irish) earldom. His son was allowed to inherit it in 1678 by a bill of Parliament, and the barony and earldom remained united until the death of the eighth earl, when the earldom became extinct, and the barony went to George Thicknesse, later Thicknesse-Tuchet. In 1997, the title went into abeyance, and remains there to this day.
