18th Regiment, Virginia Cavalry (Confederate)
18th Cavalry Regiment was organized in December 1862. Most of its members had served in the 1st Regiment Virginia Partisan Rangers (subsequently the 62nd Regiment Virginia Infantry). The unit was assigned to Imboden's and W. L. Jackson's Brigade and after participating in the Gettysburg Campaign, skirmished the Federals in western Virginia. Later it served in the Shenandoah Valley and disbanded during April 1865. The field officers were Colonel George W. Imboden, Lieutenant Colonel David E. Beall, and Major Alex. Monroe. 
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.
