upon reviewing the sources, it seems clear to me that Aenor and Alienor came to be considered equivalent by the 13th century, and the form Aenor became obsolete, replaced by Alienor (Eleanor) even in retrospect (i.e. applied to women who lived in the 11th century and during their lifetime would have been known as Aenor exclusively). It seems plausible that the "hinge" for this was Eleanor of Aquitaine, via alia Aenor, but even if this is rejected, the ultimate outcome is the same, Alienor is simply the 1200s form of what used to be Aenor in the 11th century.
So possibly this page could or should be merged into Eleanor#Origin. --dab (𒁳) 08:52, 26 November 2013 (UTC)Reply
