Regarding Titt'l: I have a Duo-Art Roll entitled "Serenade."
The composer is Titl-Krimmling.  It is played by R. Armbruster.
Although Titt'l and Titl are not too similar, since the title of
both the Duo-Art piano roll and the Estey organ roll is "Serenade,"
it would seem a good possibility that the similarity between Titt'l
and Titl might be more than coincidence.

My Duo-Art roll is currently in storage and I can't easily get it
out.  However, the number of the roll is 065547 if someone has
a copy available.
