I think you are looking for members of the Hinthorn(e) family.The descendants of John Henthorn and Margaret Downard all spelled their surname, Hinthorn.We don't know why. Later generations use either, Hinthorn or Hinthorne.
Stepen Hinthorn had a daughter, Mary Hinthorn, born 1 Jan 1830 in Money Creek Twp., McLean Co., IL.On 9 Jul 1847, she was married to John Thomas in the same county.We don't list any offspring yet.
By the way, many descendants of the Hinthorn family still live in McLean Co., IL where the largest city is Bloomington/Normal, IL.
I have been working on the genealogy of the Hinthorn(e) family for many years.
