Cyril was a very distant cousin -- and yes, 3rd cousin, twice removed is the way genealogy software describes the connection which is available from family trees online: Samuel Langhorne Clemens and Cyril Coniston Clemens are 3rd cousins 2 times removed. Their common ancestors are Ezekiel Clements (sic) (b. abt. 1680) and Christina Castell. To answer Martin's original question -- Chapter 54 of LIFE ON THE MISSISSIPPI and the entry for "Clint Levering" in the Biographical directory in HUCK FINN AND TOM SAWYER AMONG THE INDIANS, (UCal edition), p. 331-332 may be close to the source of Harnsberger's account.
