Could you link to the article? I've seen one source that suggests that
Annora de St
Valery was also known as Alianore, but that doesn't mean that there was an etymological link between the two names. She post-dates
Eleanor of Aquitaine so her family might simply have been using the name, and possibly gave
Annora as a similar-sounding nickname.
