Cyndi's List for the win. I was unable to find the symbol on Katherine Cole Shaw's grave marker through Google (I searched different combination of the letters). Through Cyndi's List I found a link for old organizations in the U.S. There was the information I needed. FECMU stands for Faith, Endurance, Courage, Modesty, and Unselfishness. It is the motto for the Royal Neighbors of America, the women's auxiliary for the Modern Woodmen of America, which her husband was a member.
