I haven't found anything either, but two _Mark Twain Journal_ articles offer possibilties on where you might wish to look: 1) Isabelle Budd's (fall 1985) investigation of "The Relation of Mark Twain to Cyril Clemens" cites as sources Raymond Martin Bell's 1984 _The Ancestry of Samuel Clemens, Grandfather of Mark Twain_ and P. O. Selby's 1973 (Northeast Missouri State U.) _Mark Twain's Kinfolks_. 2) Lucius M. Lampton (another Twain cousin) wrote of Twain's Lampton Kin (fall 1989). You might try his _The Genealogy of Mark Twain_ (1990). The two _Journal_ articles do not have the answer to your question. I have not located the cited books. larry marshburne [log in to unmask]
