1880, I do find an Elisibett and William who appear to be married only a couple of years, however, not much else seems to match up to yours.
In 1916 in Toulon, Stark IL, I find death info for a William Robert Burton who died Apr 3 1916.
Family trees shows Susie as "unknown" or Susie T Burten.
It looks to me that many of the answers you seek should be found in Stark County and you'd have to make your inquiries there.
