Sir Oliver's alleged MP webpages of ancestor are insupportable. That they have MP status without a valid source URL or attached sources is unfathomable.
Moreover, tthere's no fact-based support showing that Ellizabeth, the daughter of Eudo la Zouche, married Sir Oliver de Ingham. On the contrary, Eudo's Elizabeth married a knight surnamed Poyntz.
I once read that some profiles gain MP status when curators want to control profiles once several managers become linked to them. I find this rationale baffling. I've spent much time source-searching to see if I could validate MP webpages. Most of the time, nada.
