Dr. William M. Armstrong Hi, Sorry it has taken me so long to answer you but I have been scouring my files trying to find Dr. Armstrong. Then I went to Cook Springs on FindAGrave and found that I had left a flower on Dr. Armstrong's memorial. I was searching for my Armstrongs and I left flowers on the one's that I saw. I do not have any data on Dr. William M. Armstrong. I wish that I could have helped you.
