Yes, I've scoured GDAH and nothing there. According to Mike Musick at NARA these records should have been in the records of the Dept of the Cumberland under Union Gen George H Thomas but they simply are not there. There is no question that they once DID exist at NARA because the Kingston surrenders/paroles ARE recorded in individual soldiers compiled service records. They have most likely been misfiled somewhere in their massive holdings or may have been stolen at some past time before NARA tightened their document security.
