Hi There, I was also looking into using the name Allorah for my daughter. That was also the spelling I was looking into using. I have yet to find anything with that paticular spelling, how ever, "Alora" is apparenlty A-Laura which gets its meaning from "Laurel
". Laruel is a bush/tree that depending on what you read about it can mean a lot of different things. One in paticular is about a "peace tree". In the same manor as an olive branch. It has small dark green leaves with berries.
Hope that may help! I think the name is beautiful, I too am a Willow fan!
