Philip de de Egerton married Eilen or Ellena de St. Pierre. By one of those curious matrimonial contracts that were common to the age, we find David de Egerton, father of this Philip, in a deed dated at de Egerton, 9th of Edward II, 1315/6, entering into an agreement with John de St. Pierre, that his son and heir, Philip de de Egerton, shall marry Ellen St. Pierre, daughter of the said John, the portion of 80 marks she was to receive to be returned, as the deed prudently provided, in the event of her dying before the marriage was consummated. Happily that contingency did not arise, for she was living at the time of the Battle of Crescy was fought in 1346, 30 years after the agreement was entered into, and had borne her husband a son, David, and two daughters, Ellen and Isabel. After her death Phil de Egerton married a second wife, Maud, daughter of Richard Vernon. Philip de Egerton, like his predecessors, was an accumulator of lands. Some time after his 1st marriage he purchased from Hugh de Wardhull certain lands in Wardle and also certain other tenements in de Egerton. On account of his stature he was surnamed "the Long." He died 1362. His only son, David, did not long survive his father and died without issue, and the line of descent terminated in his two sisters, Isabel and Ellena.
