As the film was made by the Biograph Company of which Daniel's father, H.N. Marvin, was president, Mary may not have owned the movie, nor possessed the only copy. A great many Biograph pictures survive from this period and although the wedding film was not a commercial vehicle, it might be among the collections of George Eastman House or the Library of Congress, Someone interested might want to contact archivists at those facilities and request a search. Since stills of the movie were published at the time, photo agencies might have copies of those as well.
