Agathe de Geneve cannot be the daughter of Guillaume II and Alix; the dates simply don't allow it. In an Italian book called DELL ABBAZIA DI CHIARAVALLE IN LOMBARDIA (1842), we read that "Pagano ebbe in moglie Agata contessa di Ginevra sorella di Beatrice contessa di Savoia". Well, it so happens that Guillaume I and Marguerite Beatrix de Faucigny, parents of Guillaume II, HAD Margarida or Beatrice who became countess of Savoia, AND Agata. This Agata (born before 1196 and d. ca. 1247) is referred to some sources (such as Roglo) as having married a certain Enrico del Carreto in 1218 with a son Giacomo b. ca. 1220. However Pagano may have been her second marriage; one of their daughters, Ada, was b. 1232. Anyway, we must correct her parents, for she was a sister of Guillaume II and not her daughter. This much is obviously right.
