My great great uncle was Simon M.Dufur who served with the First Vermont Calvary in the Civil War and was a prisoner at Andersonville. He lived in the Richford, Vt / Glen Sutton, Quebec area. He wrote a book, Over The Deadline Or Tracked By Bloodhounds, which was an account of his captivity at Andersonville.
My great great grandfather was Eliphalet Dufur (Jr. I think). He lived in Glen Sutton, Quebec. His wife was Philista. His obituary mentioned his father, Eliphalet Sr. and stated he was the father of five Civil War soldiers..
I have previoiusly replied to Patsy Dufur at firstname.lastname@example.org. I got a non delivery message. Her message seemed to indicate that her relative was one of the five sons of Eliphalet Dufur.
