That's what I get for trusting wikipedia. You are absolutely right, and prompted some deeper research. [Before I corrected it, the blog post said "Silver Dollar" was one of Haw's nicknames...]
In "Silver Dollar, the Story of the Tabors," David Karsner reports that William Jennings Bryan, the Politician and speechifier famous in the latter part of the 19th century, visited the Tabors shortly after their second daughter was born on January 5, 1890.
Hearing the baby gurgle, Bryan exclaimed: "Why Senator, that baby's laughter has the ring of a silver dollar!" The Tabors hadn't decided on a name yet for the girl, and this was the inspiration for what her name finally came to be: "Rosemary Silver Dollar Echo Honeymoon Tabor."
After working as a newspaper reporter in Denver, Silver Dollar was ready to write her novel, which propelled by her famous name, would catapult her into fame and fortune.
Moving to Chicago, and living on the super-cheap, she set to work. Karsner says: "The best that can be said of Silver's book is that it was printed - not published." It was wildly unpopular.
Silver Dollar worked her minor celebrity for all it was worth, but after a string of burlesque and "acting" jobs, she came to a bad end. The one-time "Girl of the Nile," says Karsner, liked heavy drinking and "Happy Dust." Going by the name of Ruth Norman among many other aliases, after the men who supported her, she died at the age of 35, in 1925, by spilling a large kettle of boiling water on herself while she was extremely intoxicated.
Sorry about the sad ending. Thanks for the correction - I'm going to go edit wikipedia now...
