Sir William de Molyneux, Knight, Lord of Sefton

Sir William de Molyneux was the son of Adam de Molyneux, Lord of Sefton, and wife Letitia de Brinley. He was born c.1202, probably at Sefton, Lancashire, England, and died in 1289. He married Margaret, daughter of Sir Alan de Thornton, Knight, of Leicester. They had three sons, Richard, William and Simon. He is buried at Canterbury Cathedral, Canterbury, Kent, England.

Sir William was knighted by Phillip de Ulceby, Sheriff of Lancashire, in 1256, and held, by knight's service 15 libralas Terrae, equivalent to 3,600 acres. He succeeded to the lordship of Sefton upon his father's death. One source claims he became a Knight of the Garter. This is unlikely, as the Order of the Garter was not established until 1348, long after Sir William's death.
