So just for a second let's throw away what we think we know about Eleanor. Let's assume that the parts of Aenor and Alienor are Old French in origin.
A|enor "Very honorable" "Going in the direction of honor / honor bound" [Piety]
Ae|nor "Noble Northerner" "Northern Spirit" (a bit stretched) [Nobility, Heritage]
Ali|enor "Nurterer of Honor" or "Honorable nurterer" or "Honorable Mother" or "Mother of Honor" [Motherly/Duty]
Alie|nor "Northern Ally" "Uniter of the North" "Northern Uniter" [Politcal]
I think this is interesting and maybe a little compelling. I think it's feasible. It's simple.
