Here is something I found kind of weird.
Geoffrey II, Count of Gâtinais, Simon I de Montefont, John de Beaugency, Lord La Fleche, Ermengarde of Anjou, Duchess of Burgundy, and Geoffery III, Count of Anjou, apparently all had feuds started with Aquitaine independently (Dukes of Aquitaine were also Dukes of Gascony and it was interchangeable). This continued into their successors. For example Geoffrey III didn't get along with his bother Fulk, but apparently the feuding carried on. The feuds never got as bad the Armagnac Burgundian War, but this was due to the various counts and lords having more immediate issues than Aquitaine, not lack of hatred or lack of suspicious deaths of relatives.
Fulk IV of Anjou (Geoffrey Plantagenet of Anjou's Father and Fulk was later of Jerusalem) also started a feud with Adelaide, Daughter of the Count of Champagne, trying to smear her name.
Geoffrey V of Anjou, or Geoffrey Plantagenet continued this feuding, supplying intelligence and sometimes troops to the enemies of his targets. When the English Anarchy came up, he focused his attention on Normandy for his consort Matilda. At least three times he abandoned a successful campaigning session in Normandy when a rumor that the barons were going to rebel again. Every time he would go back and get (re)assurances of loyalty, and apparently no one could say no to his face, even if he went into a baron's castle with only 30 knights and was outnumbered by the garrison of the baron, apparently no one could say no, even if they were conspiring with the wannabe rebel ringleader the previous month.
Eleanor of Aquitaine became duchess by the time Geoffrey Plantagenet decided he had better things to do than continuing his predecessor's feuding. When they met personally, Geoffrey decided all was well. It was a good thing too, because she would alter become his daughter-in-law, albeit after his death.
Now my big question is why? I have no idea why these people got the feuding started, but to me reconciliation seems obvious. These people were either unlanded (Ermengarade) minor lords (John), or counts (Fulk IV). To keep a feud going with a Duke seems incredibly stupid, even if the duke started it by snubbing their honor, cheated them out of a deal, or maybe was responsible for the mysterious death of a nephew. Fulk also managed to piss of the daughter of a Count who had the ear of his liege lord, and she would later become queen. Why?
