A Chicago Tribune article of 1882 describes the plight of William Neil Dennison's poor family, left back in Ohio after the Colonel's journey west, uncared for, living off the generosity of Dennison's parents, his wife forced to perform on stage to feed her children. "She has four children, ranging from 4 to 9 years of age, and a husband living in Denver, who neither writes nor sends her a dollar, oblivious to her existence and to his four children. Gentlemen returning to Columbus who have seen him in Denver report that he makes money fast, and, in his princely style, anybody can share it with him—except his wife and children.Later in June of 1896, Horace Tabor was forced by the court to sell his opera house in Leadville, and the only bidder was — Col. Neil Dennison." http://www.blongerbros.com/graftersClub/bios/Dennison.asphttp://www.blongerbros.com/graftersClub/bios/Dennison.asp
