Mrs. E.F. Holmes was also known as Utah's Silver Queen. Her biography can be found in the following link:
Susanna epitomized an era of quick fortunes and expansive living from the gay nineties to the early nineteen hundreds. "Susie" to her friends, but "Utah's Silver Queen" to society writers, she was lauded by Washington newspapers as entertaining like a princess. Her exquisite gowns, rare jewels, and her $10,000 circular charm of platinum and diamonds were of paramount interest. She spent a great deal of time in Washington, much to the delight of that city's socialites who considered her vivacious, witty, sparkling, charming, and "much to behold."
