I can find no reliable sources connecting this profile, Amaury Raoul d'Arbitot (d'Abbetot, as husband or partner to Agnes de Ponthieu who has however been identified as wife of Robert de Montgomery, 3rd Earl of Shrewsbury and daughter of Guy I, Comte de Ponthieu and the curator alerts us to her NOT being married to Robert d'Arbetot Despencer but to Robert of Bellême.
I propose that she be disconnected from this erroneous husband. There seems to be scant evidence of some further connections up this tree as well and little information in the overviews to support such connections.
Mathematical.com relies much too heavily on tertiary sources. Sometimes they're the only game in town, but if you can find primary sources (contemporary accounts and records), or a good secondary source that includes relevant excerpts from primary sources, you're on much safer ground.
They can be found in surprising places, like (secondary) accounts that trace the ownership of land. And who would expect something with a title like "An Essay towards a Topographical History of the County of Norfolk" to be chock-full of genealogical information?
