There were two militia regiments from Hempstead County, the 8th and the 69th. We don't have muster rolls or payrolls for either. We do have lists of their elected officers and I checked the copies of the list which I have and did not find the name of your relative as a officer in either regiment. Sometimes when people indicate that at solider was in the militia, they are really referring to the home guard, but these were two separate organizations. The militia rolls that exist on Fold 3 are primarily from the spring of 1862. Here is a little information on the spring 1862 militia activations:

On February 17, 1862, General McCulloch issued a proclamation from Fayetteville:

“To Able-bodied Citizens Of Western Arkansas: The troops under General Price and myself are falling back before a superior force to the Boston Mountains. Thousands of Federal hirelings are within the line of your State, -whilst hundreds of men remain at home, notwithstanding their services are needed. Let every man turn out and form companies, and rally to meet the advancing enemy. Rally at once or it will be too late.

Brigadier General N. B. Burrow, commander of the 3rd Brigade, 1st Division, Arkansas State Militia reacted by activating his entire brigade. According to pay records and muster rolls from the period, the following elements of the 3rd Brigade were activated in the fact of the Union invasion of Northwest Arkansas:

5th Militia Regiment, 3rd Militia Brigade, Crawford County, on duty 21 February -17 March,
7th Militia Regiment, 3rd Militia Brigade, Franklin County, on duty 22 February -19 March,
10th Militia Regiment, 3rd Militia Brigade, Johnson County, on duty 20 February -19 March
51st Militia Regiment, 3rd Militia Brigade, Sebastian County, on duty 4 March - 19 March,
58th Militia Regiment, 3rd Militia Brigade, Logan County, on duty 22 February - 21 March,
62nd Militia Regiment, 3rd Militia Brigade, Johnson County, on duty 22 February - 1 March,

The State Military Board issued an order to Brigadier General George M. Holt, Commander of the 2nd Brigade of Arkansas Militia on February 26, to organize and put in camp each regiment in his militia brigade without delay. Brigadier General Burrow of the 3rd Militia Brigade, wrote from his headquarters at Van Buren to Governor Rector on March 2 informing the governor that he feared that only about 1,400 out of the 4,800 men enlisted in the brigade would report for duty. This estimate was based on the first returns from the units he had called out in response to Brigadier General McCulloch’s call. Burrow indicated that reasons for this poor showing were that many had responded to General McCulloch’s call by simply joining the existing volunteer regiments. Others had gone into hiding in the mountains in order to avoid militia duty. Finally some had joined the quartermaster department as teamsters and runners, and thus became exempt from militia duty, in order to escape combat.

In response to the call of the State Military Board, elements of the 2nd Brigade, Arkansas Militia were mustered during and immediately following the Battle of Pea Ridge. The 50th Militia Regiment, of Prairie County, mustered March 7–9 while the 15th Militia Regiment, of Pope County mustered on 10–11 March. These are the only 2nd Brigade units for which pay roll records are available.[305] H.W. Sholar of Greene County wrote to Governor Rector on 13 March, concerning Rector's recent call for 1,500 men to enlist in the militia. Scholar reported that companies were being raised in the county, but he complained that the men who refuse to enlist are threatened with death and "mob law" reigned in the County.
