It is very hard to look at someone and say they are this race or that. It is a matter of perception.. With the way she is dressed and her facial features I would have said she was Spanish. I looked at the final Dawes roll. There are 3 pages of Wallace's. The closest any name to your line was a George Blanchee Wallace age 7 but not George R. Wallace. I saw no Wilhoit or Leffel names on the list. 1% may or may not be correct. Sorry not much help.
