I think it may be the same person. I believe in Harrison Co MO book there was a misprint and showed Ruth M Newell.
I have marriage cert showing:
David N Williams
Ruth M Jewell
1 Oct 1848 St Joseph, Indiana
Benjamin Franklin 1851
Viola "Flora" 1852
Theodore Linus 1856 Note : Louella & Theodore were twins
Nelson Bryant 1871
If this matches your info except for spelling of Ruth's maiden name please contact me. Love to compare inof and try to break this brick wall!
I have public tree under Bartlett-Williams
