Series I: Telephone Business, 1903 - 1935

This series contains account books, lists of customers and other records from Mack's telephone business. From about 1903 to 1916 Mack and six partners built a line (the Hibbler-Mack line) from the western limits of Romeo across what is now 32 Mile Road, to the county line at Dequindre Road, then north to Leonard. Three years later Mack and other partners formed the Mack Roadway Telephone Company, with a line that ran from Romeo across 32 Mile Road then branched southward to Washington Township. That line was sold to Michigan Bell about 1929. Mack was a meticulous record-keeper, and these records contain a wealth of information on the spread of telephone lines in northern Oakland and Macomb Counties.
