Elizabeth de Lisle, wife of Sir Edmund de Stonor, was almost certainly the daughter of Sir Gerard de Lisle [died 1360], by his 2nd wife, Elizabeth le Strange, and not by his 1st wife, Eleanor de Arundel. The reasons for this are chronological in nature.
Referring to Sir Gerard de Lisle's first wife as Eleanor Fitz Alan is a misnomer. VCH Surrey 1 (1902): 348, footnote 1 correctly observes that Eleanor's father, Edmund, Earl of Arundel, is “commonly called Fitz Alan but the real designation of the family was then de Arundel.”
A good example of this name change is found the following record in which Eleanor's sister, Alice, is styled Alice Arundel, not Fitz Alan:
Dugdale, Monasticon Anglicanum 4 (1823): 141 (Walden Abbey: “Alicia Arundell [wife of John de Bohun, Earl of Hereford and Essex] sepelitur apud Walden, in medio capellæ beatæ Mariæ”).
The matter of the maternity of Gladys and Margaret, daughters of Llywelyn ap Iorweth, Prince of North Wales, is discussed at length in my book, Royal Ancestry, published in 2013. There is good evidence that Gladys was a legitimate daughter of Prince Llywelyn, by his wife, Joan of England. The maternity of Llywelyn's daughter Margaret is uncertain.
