A quick search shows no such origin. The closest is "A group including many former Confederate veterans (I'd guess that a high proportion of men in the south at that time were Confederate veterans, so that should be no surprise, and probably of no special significance) founded the first branch of the Ku Klux Klan as a social club in Pulaski, Tennessee, in 1866." at http://www.history.com/topics/ku-klux-klan
