Daisy Debolt lives somewhere in the Bulkley Valley/ Burns Lake/ Telkwa area of north western British Columbia, (about half-way between Prince George and Prince Rupert on Highway 16, if you have a road atlas handy)
Telkwa is local famous (or infamous) for the high percentage of talented bluegrass-oriented musicians who live around that fine community.

Daisy DeBolt has had at least one CD out in the past few years, and you might be able to contact her by sending a request either to CBC Radio in Vancouver or the main office in Toronto, Ontatio. You could also find her by emailing the library system in that area.
I've heard cuts from her recent CD and it's worth trying to acquire.
Barring that, you can track her down through the performing rights organization, SOCAN, via either their Vancouver or Toronto offices.

I haven't heard anything about Fraser since the late '70's.
