Richard: I don't have a Mary Elizabeth Jackson in my records born in 1850-60. Our line settled all over IL though and could be a cousin not yet found, as Mary Elizabeth or Mary or Elizabeth or Mary E. are common first names in our branches that I do have some info on. I am not sure that I followed your message correctly. It was almost as if a part of a sentence had been deleted. Good luck, let me know if I can be of further service.
