Commentary
Langston states that Joan de Vere and her husband William de Warrene died on the same day, December 12, 1286. He then also states that their daughter Alice de Warrene was born about 1287. Weis lists Joan's date of death as 1293. Langston must have made a typo by repeating William's date inadvertantly.
