Research Notes:
said to have m(1) Guillaume VIII, duke of Aquitaine (VI of Poitou), but other authors do not mention this marriage [Ref: HenryII fulk0004 5/11/2006]

Ermengarde's supposed first marriage was questioned by Morice (1750), 987. The lack of other evidence, along with the error regarding Ermengarde's mother, suggests that William of Tyre was confusing the marriage of Guillaume's parents Gui-Geoffroy of Poitou/Aquitaine and Hildegarde of Burgundy, the latter a half-sister of Foulques IV (a link of which Morice, like many modern authors, was unaware - see the page on Ermengarde mother of Foulques IV). Indeed, since Guillaume and Ermengarde were first cousins, any marriage between them must have been brief, if it took place at all. [Ref: HenryII fulk0004 5/11/2006]

1116: retired to a monastery in Jerusalem after the death of their son Geoffrey [Ref: Keats-Rohan DD p224]
