The Lordship of Bromfield and Yale was formed in 1282 by the merger of the medieval commotes of Marford, Wrexham and Yale. It was part of the Welsh Marches and was within the cantref of Maelor in the former Kingdom of Powys.
The lordship was originally bestowed on the Earls of Surrey of the Warenne family. In 1347 it passed to the Earls of Arundel of the Fitzalan family. In 1415 the male line went extinct and the lordship was divided between three and eventually just two branches of the female line of the Fitzalans.
