NORA
      L
====
ARON

N=(1,2,3).
If N=(1,3) L,A odds, but not (1,5,9). So L=(3,7)
But L=3 =N=1 =>A=7 and L*N would not reach A
and
L=7=>N=1 =>A=3 and L*N would exceed A.

So N=2 then L=(3,4)
If L=3 then A=4 The L*N=(6,7,8) not 4. impossible
If L=4 then A=3 Then L*N=(8,9) not 3. imposible
       or  then A=8 This is posible.

2**8
      4
====
8**3

O=(1,2) to conserv the values of thousands. => R=7
If R=7 O=1

Then
2178
      4

8712 

I'm glad to have solved that lot of words of Charlie's list.
