I'd say that there is no connection between Little Wonder piano
rolls and Little Wonder records.  The records were a product of the
Columbia Phonograph Co. ( http://www.littlewonderrecords.com/ ) with
some connections to the Emerson Phonograph Co.  Neither firm had
any piano or piano roll connections.

The term "Little Wonder" is a pretty common one, I've even seen a
Little Wonder electric fan from the 1900s.
