William Edward Rider:
1880, Camden, Ray, Missouri.
1870, Camden, Ray, Missouri.
1860, Richland, Lykins, Kansas Territory.
NPS S&S has a Geroge Rider listed with Quantrill as well as a John W/M Rider but I've nothing to confirm the person in the grave is the one listed in the file. It sort of stretches my imagination that this "George W Rider" was the George Rider of Quantill's company.
This site has an extensive survey of Lobb Cemetary and Uhlig and Houts who surveyed the cemetary in 1933 along with Warren Welch's Quantrill reunion lists do not identify this George Rider as being with Quantrill. They also record the date of death as 1876 not the current marker's 1880.
