Published by The Tent, 1994 I am 90 % sure this is the book I copied a Lincoln Co. section from yrs. ago. I forgot to bib.it

p. 193 states in early 1861 "It should be noted 40 men of the area (Lincoln) enlisted in the 7thMO volunteers...mustered out in 1864, they re-enlisted in the 11th"

By the way, I commend you on your attention to details and helpfullness. I am searching for a John Riley Thompson b1837 d1920 from New Hope Lincoln Co.

A biography of his son says this about J. R. Thompson " Together with a company of other men in Louisiana, Missouri, he is the owner of a line of river steamers, and they are conducting a thriving business in that line of industry. (after the war)....Mr. Thompson served in the Union army as captain of a. company which he raised for the service, and did valiant duty for the cause during the period of his enlistment.(during the war)" http://www.memoriallibrary.com/IL/South/Bios/T/Thompson~Sam.htm

I also find a 2nd Lt. John R. Thompson in the MO State Guard Greens Reg. that might be him. I just cant find any concrete records so I am going to research the units you listed. thanks so much
