Sorry, I have found very little about the Heft families in Hocking or Fairfield counties of Ohio.
I have settled the spelling of our Dorothy's (Dolly's) last name:1804, 24 Mar, Harrison Co., WV Marriage Bonds, 1803-1875, FHL #847274, film of original record:Presley Frazier and Christopher Heft gave bond for intended marriage between Presley Frazier and Dolly Heft, dau of Christopher Heft.Signed by Presley Frazier and Christopher Heft.(There is no doubt about the spelling of Heft in this record.).
The Fraziers used the spelling Frasure after they moved to Ohio.
I can only assume that Daniel Heft and other Hefts in Hocking Co might be somehow related to Dolly, but have not done any deep research on the matter.
