Looking for Marilyn Austin Smith and/or Celia Smith

I am looking for Marilyn Austin Smith and/or Celia Smith who compiled and researched a booklet (self published, I believe) in 1994 called: "Mary Gardner and Her Family". It included history and geneology of Gardner, Sweeten, Luckham, etc. I wish to know who hired them to do the research. They could possibly be from Salt Lake City, Utah.
