The identification of Jean Clemens in the 1909 Edison film makes it
very unlikely Isabel Lyon or Ralph Ashcroft were also there.
My best guess is the film was made sometime between Jean Clemens's
return to Stormfield (26 April 1909) and Clara's wedding (6 Oct 1909).
An examination of the June 1909 correspondence with Edison Manufacturing
might provide more details (as listed in the online database of
Mark Twain's letters.)

I have tried to identify the unidentified male in the the Edison clip
in the past.  The possibilities I worked with were Claude Beuchotte
and another local young man who served for a short time as a butler.
I don't see that the unidentified male bears any sort of resemblance
to Ashcroft.
