It was William, the younger, that served in these two units I suspect. Most likely kin.

Based on the Federal Militia Act of 1792, the Virginia militia system declared that all males between the ages of 18 and 45 years of age were liable for military duty. Men enrolled in the company and regiment of their home district and served as members of the "line militia", supporting the regular army troops. With the outbreak of hostilities between the North and South in April, 1861, Virginia rapidly organized the existing militia units into five divisions, 28 brigades, and 198 regiments. Captain William Wolford, a native of Hampshire County, began his service in the 114th Virginia Militia Regiment on July 14, 1861.
Commanded by Colonel Alexander Monroe, the 114th Regiment (approximately 150 men) formed a part of the Third Militia Division, under the overall command of Major General Thomas Haywood. The regiment served with Thomas "Stonewall" Jackson's corps, participating in the advance on Romney, West Virginia (September 23-25, 1861) and the skirmish at South Branch Bridge, West Virginia (26 October, 1861). The regiment was disbanded in April 1862, with the surviving members volunteering to serve in either the 18th Virginia Cavalry Regiment or the 33rd Virginia Infantry Regiment. Captain Wolford's association with the 114th ended on April 7, 1862.
