I am seeking information on the 6th Georgia Cavalry Regiment.It was formerly part of Smith's Legion. I would like to know if any histories of the regiment have been written about it. My g-g-granduncle William R. Garrett was a member of the unit. He had three other brothers in the 52nd Georgia Infantry and three in the 11th Georgia Volunteer Infantry, attached to the Army of Northern Virginia. One of whom was my g-g-grandfather Jackson L. Garrett. Thanks for any help.
