7th Regiment, Virginia Cavalry (Ashby's) (Confederate)
7th Regiment, Virginia Cavalry (Ashby's) was organized during the late spring of 1861. Ten companies formed the 12th Regiment Virginia Cavalry, seven became the 17th Battalion Virginia Cavalry, one transferred to the 14th Regiment Virginia Cavalry, and one became J.W. Carter's Battery.
Later the regiment was involved in Early's Shenandoah Valley operations and disbanded in mid-April, 1865. None of its members were at Appomattox on April 9. The field officers were Colonels Turner Ashby, Richard H. Dulany, William E. Jones, and A.W. McDonald; Lieutenant Colonel Thomas Marshall; and Majors O.R. Funsten, Daniel C. Harcher, and Samuel B. Myers. 
Companies in this Regiment with the Counties of Origin
Men often enlisted in a company recruited in the counties where they lived though not always. After many battles, companies might be combined because so many men were killed or wounded. However if you are unsure which company your ancestor was in, try the company recruited in his county first.
