Per Wikipedia, “Aenor” may itself be a corruption of “Adamardis”, apparently a feminine form of “Ademar”. “Ademar” is a masculine Germanic name, ultimately derived from “Audamar”, from the elements aud “wealth, prosperity” and mar “fame”.
We actually know that Aenor is a simplified version of Adenordis, the Latinization of a Germanic name which we do not know. However, we think it may be derived from Ademar.
