Thanks for your offer of help. I do have access to both the book on the 4th NC Cav. and to Manarin's volumes.
Are you interested in the regiment?
My own interest is on the Siege of Petersburg and the Appomattox Campaign and currently I'm interested in Barringer's NC Cav. Brigade and also Dearing's old brigade which was under Roberts in March and April 65.
