Bruce;

I suspect John T Crump 1845-1927 is one. He is listed in Warren Welch's list of Quantrill men but served in Shelby's brigade

A second is Gabriel C. Parr again on Welch's list and identified as being in Shanks Reg, Shelby's brigade

Both are buried in Lobb Cemetery

Taking a cross reference of Welch's 1911 list I come up with:

Andrew Forgy Hays
Maurice Jacobs

Robert "Bob" Thompson listed as being killed near Booneville while scouting with Welch in 1863 also is listed as Shelby's Brigade
