About Ranulph "Conqueror" de Mesnilwarin
1. Ranulphus de Mesnil Warin
Ranulphus - was one of the thirty-two persons to whom William the Conqueror gave the most part of Cheshire, and had given him fifteen lordships there, among which was Peure, now callled Over Peover, and which was the seat of the family for many generations.
The Mainwarings (pronounced "Mannering") held the manor at Peover Hall from the time of the Norman Conquest. Ranulphus, believed to be the family's ancestor came to live in Over Peover (pronounced "pee-ver"). The present Hall was built by Sir Randle Mainwaring in 1585 and had a Georgian extension built by Sir Henry Mainwaring, the last male heir of the family. In 1797 the house was purchased by Thomas Wettenhall, who took the name of Mainwaring guaranteeing that the house would continue in the family name until 1919 after which it was owned by several other unrelated families.
