Ethel Mae Farney rests in the Sterling Mennonite Cemetery in Reno County, KS.
Update 10/27/08: I received my copy of Douglas Keister's new book "Forever Dixie" and was happy to find a similar picture of this symbol on page 166. It is a boat. According to Keister "...the boat also suggests a return to the cradle or womb..."
I have looked at this stone many times trying to determine what it means. I think I now have my answer.
