Nanci Griffith was an interesting combination of Southern lady and rabble-rouser.
It doesn't surprise me to find that her family, friends, and management are protective of her privacy.
Thanks, GUEST, for the link: somehow, that Austin360 website sneaked away from me, as I was attempting to link directly from the Statesman webpages, which was not permitted.
If you don't care to read the entire article, this excerpt might partly answer one question.
"On Tuesday (24 August), Griffith's manager, Burt Stein, issued a brief addition to the original (13 August) statement: 'Nanci's wishes were for no funeral or religious ceremony to be held in her name. She asked that, in lieu of flowers, to make donations to Vietnam Veterans of America Foundation, the Mines Advisory Group of Manchester, England, or The Store in Nashville, Tennessee."
