The Political History of England, Vol II, George Burton Adams Longmans Green and Co, 1905, Ch VII, p158:
 "...A few days later a treaty was made at Gisors, with the king of France. Louis formally conceded to Henry the overlordship of Belleme, which had not before depended upon the duchy of Normandy, and that of Maine, Britanny. In the case of Maine and of Britanny this was the recognition oflong-standing claims and of accomplished facts, for Count Alan Fergant of Britanny, as well as Fulk of Anjou, had already become the vassal of Henry, and had obtained the hand of a natural daughter of the king for his son Conan, who in this year became count..."
Ch XIV, p297:
"...[Henry's] hold on Britanny was strengthened by the death, in February, 1171, of Conan the candidate whom he had recognized as count. Since 1166 the administration of the country had been practically in his hands; and in that year his son Geoffrey had been betrothed to Constance, the daughter and heiress of Conan. Geoffrey would now succeed to the countship, but he was still a child; and Britanny was virtually incorporated in Henry's continental empire."
