I see that your post was in 2001, but am hoping you'll get mine.
My great grandmother was Daisy E. Hefner (born abt 1871, IL) who married Marton or Marston Hefner (abt 1834, IL) mar Mary P. Wood(?).
Possibly his parents were Michael Hefner mar. Barbara Flesher)
My grandmother was Daisy Roberta Smith, dau of Shelton Lawrence Smith and Daisy E. Hefner. She married my grandfather, Howard Rice Hardwick.
I know that the Hefner name was also spelled Heffner. I hope you have some info on my Hefners.
