Two years ago, I gave an explanation about Alienor:

Later, I worked more on the subject, I wrote a paper about the genesis of the name Eleanor and its variants and I sent to the Societat d'Onomàstica (the Catalan Names Society) to be published. Right now, it is in press and they have assured me that it will appear in the next bulletin, which must to come out next March or April.
If you are interested in it, sent me a PM with your e-mail address and I will sent you the paper and an English translation when it is finally published.
