The Pike County Home Guard consisted of eight companies commanded by Col. George W. Anderson and existed from May thru September 1861.
The Fifth Missouri State Militia (Six Months), was formed in Pike County and consisted of seven companies of infantry, three companies of cavalry, and one company of artillery (Red Rovers), all commanded by Col. Thomas James Clarke Fagg. It existed from August 1861 thru January 1862. Company E, commanded by Capt. James Reid, was primarily from Lincoln County, while the other companies were from Pike County (with men from Pike County Ill. supplementing the ranks). This version of the Missouri State Militia is not to be confused with its pre-war, Southern-supporting MSM, nor with the later Union-supporting MSM (see below).
Note that John B. Henderson, who grew up in Lincoln County and later became a nationally prominent statesman based out of Pike County, was appointed brigadier general of state troops in northeast Missouri’s Second Congressional District in August of 1861, and served in that position until he was appointed to the U.S. Senate the following January (where he went on to author the 13th Amendment that freed the slaves). Both the Pike County Home Guard and its successor, the 5th MSM (Fagg’s), would have been a part of his command during the period he served.
The 10th Missouri State Militia Cavalry Battalion was formed in Pike County in December 1861. It initially consisted of five companies---A, B, C, D, E---made up of men from Pike Mo., and was supplemented by men from Pike Ill. It was led by Col. Edwin Smart, a retired career soldier from the U.S. Army who was residing in Pike County when the war started.
Morsey’s Mounted Rifles Battalion was formed in December 1861. It consisted of three companies---A, B, C---from Montgomery, Lincoln and Warren counties respectively. The battalion was led by Warren County’s Lt. Col. Frederick Morsey, and immigrant (and former Baron) from Hanover, Germany. Morsey's Battalion was integrated into the 10th MSM Cavalry Battalion in early 1862, with Morsey’s A, B, C being redesignated the 10th MSM's F, G, H. The combined Morsey's Battalion/10th MSM Cavalry Battalion was designated the 10th MSM Cavalry Regiment. Captain James Wilson of Lincoln County was the commanding officer of Company B/G. He was later promoted to major of the regiment. While he would ultimately command two battalions of the regiment in southeast Missouri after the 3rd MSM's commanding officer was sent up to north central Missouri with one battalion, Wilson never commanded the entire regiment.
With the disbanding of the 5th Missouri State Militia (Fagg’s) in January 1862, the Red Rovers of Pike County went on to become an independant artillery company in the new Missouri State Militia, and was led by Captain Hiram Rice. This independant MSM Red Rovers artillery company was mounted and was used as cavalry, and by the late summer of 1862 was fully integrated into the 10th Missouri State Militia as Company I. Red Rovers Trivia: During the course of the war, while the soldiers of the 3rd MSM Cavalry wore the yellow-striped pants of cavalrymen, Company I of the 3rd MSM Cavalry wore the red-striped pants of artillerymen. The company was decimated at Stony Battery in Wayne County in April 1863, where its few dozen men, serving as rear-guard to the retreating regiment, went hand-to-hand against hundreds of Texans serving as the advance of Marmaduke's Cape Girardeau Expedition. Later in the war, the the unit nick-name evolved from the Red Rovers to the Four-Mile Deadshots due to a ridiculously long shot one of the company's men made against an enemy soldier.
In February of 1863 the 10th Missouri State Militia Cavalry was redesignated the 3rd Missouri State Militia Cavalry (New). It is under this later designation that it is now most commonly known. However, for research purposes you should not overlook its initial designation, lest you miss a large portion of its history. Do not confuse the 3rd MSM Cavalry (New) with the 3rd MSM Cavalry (Old). They are unrelated.
The 37th Enrolled Missouri Militia (aka Shirt Tail Militia) was formed in Lincoln County in July 1862, and was commanded by Col. C.W. Parker.
The 49th Enrolled Missouri Militia was formed in Pike County in July 1862, and was commanded by Col. George W. Anderson. The 49th EMM is not to be confused with the 49th Missouri Infantry, which recruited two companies out of Pike County.
The 1st Battalion Enrolled Missouri Militia was formed in Pike County, and was commanded by Col. George W. Anderson. While it existed contemporaneous to the 49th Enrolled Missouri Militia, and the same man commanded both units, the two existed as two distinct entities. It appears that the 49th EMM max’d out in terms of companies and troops, and the 1st Battalion was formed to take in the overflow.
In August of 1862, Company D, 33rd Missouri Infantry was recruited in Pike County. It appears that around the same time a few men from both Lincoln and Pike ended up in Company B, 32nd Missouri Infantry--one such recruit later grumbled that he had signed on with one recruiting captain, who, when he couldn't meet his quoto of men, sold him and his comrades by the head to another recruiting captain.
In the spring of 1863, the 1st Provisional Enrolled Missouri Militia had men detailed into Company E, Company G and Company I of the regiment from Pike County’s 49th EMM and Pike County’s 1st Battalion EMM.
In the spring of 1863, the 2nd Provisional Enrolled Missouri Militia had men detailed into Company C and Company D of the regiment from Lincoln County’s 37th EMM.

Company A, Company E and Company K of the 49th Missouri Infantry were recruited in Lincoln County in the summer of 1864.
Company F and Company H of the 49th Missouri Infantry were recruited in Pike County in the summer of 1864.
The two top field officers of the 49th Missouri Infantry were from Pike County.
Company F of the 18th USCT was recruited out of Pike County in mid-1864.

Regarding your references to “7th US MO 61-64” and “11th MO veterans 64-65,” I am not familiar with any recruiting in Lincoln or Pike counties by any units fitting those descriptions. If you will elaborate on your sources and provide more details, perhaps those units can be addressed.
