Kirk, I don't have access to the CP corrections volume you mention. However, in EuroAristo we tend to go with Douglas Richardson's books unless newer proof has been located (generally a discussion in the Gen-Medieval group). I haven't located anything else about a Phillippe de la Pole marrying Hugh Burnell. And if she was the daughter of Michael de la Pole and Katherine Stafford, she wouldn't have been born before around 1384-90 since, according to Magna Carta Ancestry (MCA), Michael & Katherine married circa 13 April 1383. MCA does mention a daughter Philippe, but not whom she married. I believe she should be detached from Hugh Burnell.
