I have some information on S.D. Dennis. He was my GGGrandfather. My Grandfather was Harrison Dennis, son of Wm. Henry Dennis, Who was a son of S.D. Dennis. S.D. Dennis is buried in Calton cemetery Northwest of McDowell, Missouri. He was killed by a train while walking from Monet Mo. to his home. I have copies of records where he is filing for pension. I hope this helps. Tom Brown t-brown@mindspring.com
