However, I did not use the citation you give, that is, 6:114, but rather 6:125-126. This indicates that Gaucher de Châtillon, lord of La Fère and St-Lambert, viscount of Blaigny, was married to Jeanne de Coucy, the daughter of Guillaume, seigneur of Coucy and Marle, and Isabeau of Châtillon-St-Pol. However, when you check 8:544-545 under Coucy, Jeanne is not listed as a child of Guillaume de Coucy and Isabeau of Châtillon-St-Pol.

She is not mentioned either in Europäische Stammtafeln, 7, part 2:80-82 under Coucy but is found listed without parents on 7, part 2:19, under Châtillon-sur-Marne.

According to Maxime de Sars in *Le Laonnais féodal*, vol. 4 (1931) p.
209, Guillaume, seigneur of Coucy, and Isabeau of Châtillon-St-Pol did
have a daughter named Jeanne, but she was not married - she was a nun at
Notre-Dame de Soissons, where she died on 6 July 1379.
She had a brother named Jean (died without issue after 1350) who was
seigneur of Havrincourt.
Any information ascribed to François de l'Alouëte, a 16th-century lawyer
in Sedan, should be treated with extreme caution - he called the
Austrian wife of Enguerrand VI of Coucy (numbering him V) alternately
Catherine and Marguerite, says that he died in 1344 (actually 1346),
that his wife was buried with him at Ourscamp (she married a second
husband after his death and was buried at Königsfelden), and that they
had four sons and five daughters (actually only one son is recorded
apart from l'Alouëte's inventions).
