Hi Dylan
I am sorry, I do not find a Dorothy Hupp Ward as a member of DAR. This doesn't mean she wasn't - I just do not locate her.
Are you aware of the DAR Genealogical Research System (GRS)? It is available for the public to search and is based on applicaitons submitted to the DAR since it began in 1890.
Go to dar.org
Click on Genealogy
Click on Online Research and GRS
Click on Ancestor and type in James Archer
Click on the correct James Archer
Click on the various links and you may pic, up some useful information.
Let me know if I can assist further.
