Link to Rotenberg Ledger
The Rotenberg Ledger are turn of the 20th century records of passengers who had their steamship tickets purchased by relations in Toronto. A large percentage of the names that are recorded in this Steamship Agent’s books are Jewish.
About 1908, in a short-lived partnership with Samson and Charles J. Garfunkel, the firm of Garfunkel & Rottenberg, steamship agents, opened at 141 Queen Street West, while Louis continued to operate the junk dealership.
Listed at the Queen Street address in the 1911 city directory simply as Louis Rottenberg & Sons, insurance agents, the firm had further diversified; and also expanded with the inclusion of sons Max and Louis Jr. in the business. By 1916, they were advertising themselves as L. Rotenberg, bankers, steamship and insurance agents, apparently with the departure of son Henry. However, in the following year the Rotenberg family abandoned their steamship agency.
The surviving Rotenberg Ledger is a register of steamship passengers who had their tickets purchased for them by relatives in Canada—generally living in the Toronto region. The majority of the names are of Jews who were emigrating from Eastern and Central Europe. Thanks to Cyril Gryfe for providing the above provenance to the Rotenberg Ledger.
