Who created and published this directory? Was this before the days of phone books? So this brings data on Schwartz up to 1911.
Most cities published directories prior to the phone books. They listed the addresses of people and businesses. They were also filled with advertising. Sometimes they would list death dates if a person had died during the year since the last directory had been published.
