I want to know the history of the naming of the Waltz Move called the
Twinkle (basically when named, why would they call it this, and who
created this name if it is applicable to a person - or is there some
other story behind it).

The closest I have come to answering this is just a definition
(Twinkle: A step in any direction followed by a close and a step in
another direction -- actually from a book Complete Book of Ballroom
Dancing). Even though this is a broad definition, I have only heard
the term used in a very common American Waltz move from a progressive or box
into a promenade -- and thus I am interested in this applicability. I
do not know if this move predates the modern waltz in the 20th century
or might go back to the Viennese waltz in the 1800s (I assume it is likely a
20th centurn move once the modern/slow/boston/American Waltz came into
being). There are many sites and books with basic history on Waltz,
but I am trying to find this specific answer to the actual background
for Jill - a dance instructor friend of mine.  The move does change (like a
twinkle'ing star I suppose) but it would seem with a name that
specific the name and move would have a pretty definitive history.
Thanks.

Hmm - I never heard of this term before, but it makes me wonder - is
this where the term "Twinkle Toes" comes from?
