Lisa, be careful about assuming that Denson=Denton. Franklin County had many, many families within the surname, Dunston/Dunstan (from whom I descend). I do have Wiliam AND Wilson Dunston as ancestors. You must be sure that all other family info matches up before you can decide that the transcription is wrong, or that the enumerator misspelled the surname.
Also, Delores is right about the estate files being online. (I helped to transcribe them!) :) Also, there may be something on the NC genweb site.
I do physically go to the area to do research from time to time, sonif you need some specific lookups, you can email me at firstname.lastname@example.org
, and I can try to help you when I go, again.
