Yes the Edison film does exist. It is reprinted frame by frame in the book "Mark Twain in the Movies" by John Seelye - i.e., you can flip the pages and see him walk up. I don't remember a daughter in the picture though. Don't have a clear memory of ever seeing it as a film, although it just might be in the film Mark Twain's America, which was produced in the 50's - a standard holding for those universities that still have 16mm film libraries.
