STONAKER Temperament

[Wstonaker@AOL.COM]

   Sorry this may be off topic, but I'm looking for any information about the
William Stonaker who developed the so called "Stonaker Temperament".

    I don't think that there is a close family connection but it is curious
that my grandfather, Frank H. Stonaker, was a music store owner and piano
tuner in Indiana in the 1920-1940 era.

Any leads would be most appreciated.

            Regards, Bill
