Lou Perry—known as “Big Lou”—was from a troubled family. Her real name was Louisa Dorff, and she was born in West Virginia. Around 1870, the family moved to Cincinnati, where her two brothers, Charles and Samuel, got into trouble and were sent to the penitentiary. When they returned from prison, they got into trouble again, and the family was driven out of the city. Lou stayed behind.
The Illustrated Police News politely referred to Lou as a “kept woman.” The Cincinnati Daily Star was a bit harsher: “She went from bad to worse and finally became a low, miserable, besotted prostitute.”
