Ramblings of General Geekery

I found a pioneer cemetery with several freemason graves… anyone up for some ghost conspiracy adventures?

The grave of James Lamb, died 1893, with a large freemason logo on the headstone.
A bunch of graves from various times in the past century, also featuring some freemason logos.
An old 1883 grave with a wooden, painted headstone. I guess this should be called a headplank?
Another old headplank, dated 1871.
