In 1114, King Henry I gave Ellesmere to William Peverel as a part of the Maelor, which included Overton & Whittington at that time. His descendants retained Ellesmere until apparently the late 1140s when the lordship was acquired, probably by force, by Madog ap Maredudd of Powys. Madog died in 1160 and Ellesmere came into the hands of King Henry II.

In 1287, Oliver Ingham, who was an English commander and administrator in Aquitaine during the War of Saint-Sardos and early Hundred Years War was born in Ellesmere. His daughter Joan married Robert ("Roger") le Strange, 4th Baron Strange, son of Lord Strange of Knockin & Isolda de Walton.
