Monahan had spent his early years in Idaho as a
cowboy, and briefly lived in
Oregon before returning to
Owyhee County, where an 1898 directory listed him as a cattle rancher. Monahan was said to have worked in the
livery business, then a sawmill, and later saved several thousand dollars in mining, which were stolen in an investment fraud. Monahan voted in an 1880 Republican primary despite women being denied the vote at the time. Monahan lived on
Succor Creek, near
Silver City, in a small home with dirt floors, raising pigs and chickens. He is listed in three Idaho census inquiries. All identified Monahan as a male, with one marked with an asterisk with the remark "doubtful sex." Locals remarked that they were aware that Monahan was female, but Monahan never confirmed it when questioned, and the issue was rarely raised. In a letter to the Buffalo police chief seeking next of kin, a local resident remarked that, "He had fought his way through with many of us ... suffered hardship and hunger in early days and never whimpered ... the cowboys treated him with the greatest respect, and he was always welcome to eat and sleep at their camps." Monahan fell ill in 1903 after a winter cattle drive on the
Boise River and died in 1904. At this point, townspeople discovered his sex, which was widely reported in the media of the day including an exposé in the
American Journal Examiner. ==Media==
