Old publications such as newspapers, tax assessments an city directories are a rich source of genealogical history. Dedicated volunteers around the world are busy digitizing and much information is now available online - free and both fee-base. Sadly, many records were destroyed both accidently (fire) and intentionally (they could not foresee future interest). Still lots of amazing reading, though some might require a trip to the archives either physically, or via paid researcher.
Newspapers are a favourite because they let us experience our ancestors daily life and the social norms of the times. From writing style to what seem like really bad jokes today, newspapers make for a fascinating read and offer a wealth of information in social announcements such as who's visiting town , birthdays, weddings, birthday celebrations etc.
The annual tax assessment records for the City of Toronto date back to 1834 and contain much useful ancestral information including, name, occupation. salary, religion of the Head of Household as well as details of the property itself (location, value, ownership). The assessments are not available online but microfilm copies can be viewed free of charge at City of Toronto Archives. Visit the City of Toronto Archives site to learn more about what's available and when to visit. Find Assessment Roll information here. For areas outside the GTA, contact your local library.
Directories and Voters Lists
Directories and voters lists are similar to a phone book and may include name, occupation and residence of an individual. They are useful as well for spelling of a last name if you are having trouble finding your ancestor on a census document.
Directories are useful for solving spelling variations if you're having trouble finding your ancestor on a census. Voters Lists will confirm name and location and can serve as secondary information to support your find.
Digital Toronto City Directories Toronto Public Library has digitized all of the Toronto city directories in its collections that were published between 1833 and 1969.
The Rowsell 1850 Directory covers the City of Toronto and York County but other townships would publish a similar guide. This Toronto directory is PDF only but it's easy to navigate through the alphabetical list of inhabitant householders in Toronto, Yorkville and the County of York. The list includes the Name, Occupation and Address (sometimes with house number). It has lots of other useful information including advertising and is an interesting glimpse of life in the mid 19th century.
The Toronto Reference Library has old published hard copy phonebooks on the shelves for easy access. They are interesting because in the early days, the listing included occupation/place of work.
While searching, keep in mind that many streets have disappeared or been renamed since your ancestor walked the earth. In large cities especially, the street names of the 1800's will not appear on today's city maps making it difficult to pin down exactly where they lived. In Toronto, for example, Adelaide was Duke, University was College and Simcoe was William. Still other streets are no longer there! Try to find early local maps of the area (libraries should have them) and compare the area you are interested in to a current map today. Wiki and Google are useful as well. It's usually not too difficult to find the current name. Just something to keep in mind if your search for a street comes up empty.
