Research / Disputed
Updated as of Jan 2021 (please use the tilde feature when updating)
Benjamin may be the son of Raleigh Rawley Duncan according to Mary Ann Dobson (MAD) notes and researchers on Geni and FHC
Disproven - No Benjamin from Wm/Rawley Group for this timeframe - The one found by MAD was the Raleigh from Marshall Duncan group and another from the Wm/Rawley group originating from BW Bible and 1886 McAffee Letter
Following is the co-mingled information from two different Duncan Groups (tree- to-tree copies apparently did not update but continued w/errors)
DNA research is providing information that the following information published in Mary Ann Dobson (MAD) notes is very likely the correct descendant line. See notes shown under DNA Research:
William had a son named Raleigh Duncan. Raleigh Duncan had a son named Benjamin Duncan. Benjamin lived in Culpepper, Virginia and stayed there until he was called to the army to fight in the Revolutionary War. He fought in the Battle of Kings Mountain. **After the war was over he m. Mary Davis in Wilkes Co. NC. Benjamin and his wife then moved to Middlesborough Ky (Knox County) and raised their family.

DNA connections are confirming that this Benjamin DUNCAN profile is from the same line as William Duncan m: Ruth Raleigh or Rawley but not from the same line as William Duncan m: Rosanna Norman. It is however becoming clear that William Duncan m Rosanna Norman are cousins to this Benjamin Duncan.
DNA research seems to confirm that Benjamin Duncan is a son of Rawley Duncan and Mary Roberts, DNA from the Mary Roberts passed down to cousins of both lines: CFish Gedmatch A620132 a descendant of Mary Robert and Sean Bamman Gedmatch A481004 descendant of William Robert, common ancestor John R Roberts IV and Elizabeth Lobell Russell who share 16.0 cMs on chr 12.
More information is needed to confirm with triangulation these relationships. If you have any information that would help, please contact the Duncan Name Study.
Suspect the problem here is McAfee Letter of 1888 and the conflict in histories re James m Asenith Browning/Charles m Bourne/ Rawley m McLain. Charles reportedly had son Benjamin.) Rawley #6 Multiple Marriage Dispute - Most indicate as brothers but highly likely Charles and Rawley were brothers (via Townsend (?w/son William) and 1st cousin to James, or may be James is also a brother and the William/Rawley should have a separate James.
Likely the Browning and Davis are or s/b the DNA cousins - many intermarriages Duncan/Norman/Browning/ families etc. (John Davis appears in court Records for Elizabeth Browning) - Mary Davis is Sister of Revolutionary War soldier Thomas Davis. Many Trees w/wrong connections and/or tree-to-tree copies w/no sources.
No original source records have been located to confirm birth or marriage records; Several Source to Source Discrepancies. It appears that some erroneous information may have been published, and perhaps republished/reported, making the “actual facts” obscure.
