Nelly and Homer,
I'll jump in on this, as a break from other things, and maybe I can help a bit.

The I.O.O.F. is the International Order of Odd Fellows, and is NOT part of the Grand Army of the Republic for Union veterans of the CW.

Christian D Wolf was colonel and commander of 4th Enrolled Missouri Militia from somewhere in the St. Louis area. Wolf was promoted out of his colonelcy to Brigadier General and commanded his old regiment and several other EMM St. Louis outfits as a brigade commander during Price's raid starting 25 September 1864 with their sudden mobilization, as the Rebel army marched toward St. Louis. BG Wolf's brigade and a couple of other brigades were hurriedly armed and rode out through Kirkwood on the RR and on October 1, 1864, to secure the important RR town of Franklin in east Franklin County. I think this was along the Pacific RR just west of Gray's Summit, or so. Unfortunately, the Rebels, I think Shelby's cavalry, were in Franklin first and Wolf's EMM brigade chased them out of town, but not before the Confederates burned the RR depot. Therefore, if your William Braun was indeed the one in the 4th EMM, he may have seen some action. The 4th EMM was also under Brigadier General Edward C. Pike, but, from the way the reports read, Pike was under Wolf, and the bits and pieces of the various EMM units who responded to the alarm were re-shuffled into units that could be better managed by Pike and Wolf. Everything was kinda mixed up in the hurry of the approaching danger.

The online record for the Private William Braun of Company I, 4th Enrolled Missouri Militia, does not give his age. It says Braun was enrolled 25 September 1864 evidently at Washington, Mo, in Franklin County, and ordered into active service 20 October 1864 at Washington by General Pike. He was relieved from duty 31 October 1864 by General Pike. Now, that's what his record says. The EMM mobilization was so quick that the paperwork was filled in later, as the EMM units that had probably already drilled as units at earlier periods. were hastily assembled and plunked onto the railroad (mostly on flatcars, as the record reads), and hurried out west to be the first line of defense against Price's army that was already on its way. What I reported above is from BG Pike's report in "official Records," series 1, vol. 41, part 1, pages 461-464. The part of Braun's record that I DO believe is that the 4th EMM served under BG Pike with BG Wolf, the 4th's former commander, over Pike. I looked up Pike and Wolf in the index in the same volume of the O.R. cited above, and that's how I found out who was who as I described above.

By October 31 1864 the danger was definitely over for St. Louis, so most of the mobilized EMM outfits were discharged from active duty so they could go back to their civilian pursuits.

I looked at the other William Braun's in the MO State Archives, and most of those records were for the older William Braun who was in the 3-months' unit Fremont's Hussars as a sergeant and then in the 3-year 4th Missouri Cavalry Regiment as a corporal. I tend to agree with Homer that the older Wm. Braun didn't match your man, but I'm foggy on the details. Therefore, I am suspicious the William Braun who lived near or in the arsenal in south St. Louis and had something to do with Captain Bell is perhaps not yours, and very possibly the guy in the Fremont's Hussars and later the 4th Missouri Cavalry.

The 4th EMM also had a Charles Braun, but in Company B.

Clear as mud, right?
