At the end of the book "Young Reporter Mark Twain in Virginia City" by Katharine Hillyer (1964) there is an 1896 photo of Twain on a beach on the east coast. The photo cutline concludes "The photo is reproduced courtesy of descendent Samuel L. Clemens of Missouri." Was there a descendent who took on the name SLC ? Am ignorant of his descendents, and of Clara's children, if any. Can someone enlighten? Thanks Ellen
