A residential directory may contain more than a directory of residents with addresses. Some directories have specific directories after the main residential listing. Those “directories in the back” may contain additional clues about someone you are researching. This 1918 Prairie Farmer’s Directory for Hancock County, Illinois, contained several additional directories, including ones for various breeders of cattle and chickens, tractor owners, automobile owners, and silo owners.
The directory contained an unexpected reference to a relative who was living in a different county at the time. His mention in the “Silo Owner’s Directory” may indicate he still owned property in the area even though he did not live there.
