Thanks for the tip, Diane! I did not know that - sounds like I should have volunteered with the local genealogy group when they were surveying our pioneer cemetary, and I could have learned tricks like that.
I can also enhance these photos with digital manipulation if anyone wants copies. I intend to crop these and post to find-a-grave when I have time, but time is in short supply.
I've added Surnames for additional markers I photographed
