I have a tendency towards Hebrew names and I've seen
Elinor used on some Jewish children and Israeli children. Personal preference. Also, I really dislike
Eleanor and
Eleanore because they remind me of FDR's wife, of whom I am not particularly fond.
Elanor looks like you sort of forgot to add an "e" somewhere.
I don't know anyone with the name, but
Eleanor is probably the most common spelling.
