In all of my research on Sir Gilbert de Clare (Clare-14), I've never seen any other wife for him other than Adeliza de Clermont., daughter of Comte de Clermont Hugh de Creil and Margaret de Roucy. His profile has more than one wife. If anyone can provide good sources for wives other than Adeliza and/or parents for her other than those noted, please do so in the next few days.
If I don't hear from anyone with additional information by this weekend, my plan is to purge the other spouses.
