Ahh, right. They're just guessing, I'm afraid. There's no reason to think that
Aenor / Alienore contributed to
Annora or vice versa. It's not unusual for historical persons to be listed under different names even up until relatively recent times (for example, one of my fiancee's 19th-century ancestors is listed as
Hannah and
Harriet on different documents).
Alienore and
Annora sound similar which is no doubt why they were used together in this case, but it's not evidence for a linguistic connection between the names.
