There are Taliafferos (aka Tolliver) all over Virginia and NC, including s few up here in the mountains where I live. Pleased to know that a Taliaffero was at Guilford CH; four of my ancestors were there as well (one cavalry officer, two gunners, and one militiaman). Good company!
I fly my Guilford Courthouse flag occasionally in honor of my gr-gr-gr-gr Scotch-Irish grandfather who was there. He was in a Guilford County militia for much of the war and he mentions picking up bodies on the Guilford CH battlefield in his pension application. He served in Green's army at that time for 4 to 6 months as well.
Unfortunately but not unexpectedly, none of my neighbors know what the Guilford CH flag I'm flying is though I tell the ones that ask.
I just purchased the Babits and Howard new book, "Long, Obstinate, and Bloody, The Battle of Guilford Courthouse," and can't wait to have the time to get into it. I already have "The Road to Guilford Courthouse" book by Buchanan.
