O’Leary, Daniel (29 June 1846?–29 May 1933), pedestrian, was born in the village of Carrigroe, County Cork, Ireland, the son of a farmer. His parents’ names are not known.

Unable to find employment in New York City, he moved to Chicago, Illinois, and secured a job in a lumberyard. During the winter of 1866 O’Leary moved to Bolivar County, Mississippi, where he picked cotton. In 1868 he returned to Chicago and became a door-to-door book salesman.
