From a guidebook for Graceland Cemetery:
"Sometimes the stories are heartbreaking, such as the one about the family of grocer William M. Hoyt. In the Hoyt family plot, just to the north of a towering monument, is a row of five small headstones. Four of the family members in these graves died on the same day: Dec. 30, 1903. The Lanctot booklet explains that they were Emilie Hoyt Fox and her three children, ages 9 to 15, among the more than 600 people killed in the deadly Iroquois Theater fire. The fifth grave is for Emile's husband, Frederick Morton Fox, who died of grief two months later."
