R.S. McDonald was involved with the Knights of Columbus. He was issued a Traveling Card on 11/24/1919 by the Koochiching Council #1540.
This places my grandfather R.S. in Cheney, Washington by 1919.
The Knights of Columbus is a Catholic fraternal benefits society. This website explains their founding principles. http://www.kofc.org/un/en/about/index.html I called the International Falls office of the Knights of Columbus to find out if I could get more information on R.S. but they were unable to comply. You never know about these types of organizations but it is still worth a try to seek them out and inquire.
