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.
Company A (Red House Volunteers) - many men from Charlotte County
Company B ( Maryland Guard) - many men from Baltimore, Maryland
Company C (Oliver Grays) - many men from Mecklenburg County
Company D ( Cumberland Greys) - many men from Cumberland County
Company F (F Company) - many men from Richmond County
Company G (Brunswick Grays or Brunswick Guard) - many men from Brunswick County
Company H (Chalk Level Grays) - many men from Pittsylvania County
