♀Eleonore de Chatellerault

Eleonore de Chatellerault was the twenty-sixth great-grandmother of Nancy Jane Blanchard (1929–2006), by two separate lines of descent, both through her daughter Eleanor of Aquitaine (died 1204).

Wife of the Duke of Aquitaine

She is said to have been a daughter of Aumary I, Vicomte of Chatellerault, and was the first wife of Guillaume X, Duke of Aquitaine and Count of Poitou. Their eldest daughter, Eleanor, inherited the duchy of Aquitaine and became Queen of France and then Queen of England. Her mother is not known.

Lines of descent

Both lines run down Nancy Jane Blanchard’s father’s side, through Kenneth Blanchard (1897–1975), and both pass through Eleanor of Aquitaine. One runs through her son John of England (1166–1216), then John’s son Henry of England (1207–1272) and Henry’s son Edward of England (1239–1307); this is the twenty-sixth-great line. The other runs through her daughter Eleanor of England (1162–1214), then Berenguela of Castile, her son Fernando of Castile (1201–1252), and his daughter Eleanor of Castile (died 1290); this is the twenty-seventh-great line. The two lines meet again in Joan of England (1272–1307), whose parents, Edward and Eleanor of Castile, both descended from Eleanor of Aquitaine.
