Researchers with Ontario roots have reason to celebrate: The Ontario Name Index (TONI) is now available on Ancestry, significantly expanding access to this valuable resource.
For years, TONI has been available only through the Ontario Genealogical Society website. While genealogists familiar with OGS knew to search there, the collection remained relatively unknown to the broader community of researchers who might benefit from it.
Two Versions, Different Scopes
The Ontario Name Index is a comprehensive database spanning records from 1812 to 2023, created by OGS volunteers and launched in 2011. Now it exists in two locations with different record counts.
Ancestry’s collection contains 7,656,896 records—all those that OGS volunteers have transcribed from original sources. The version on the OGS website at https://ogs.on.ca/toni/ is substantially larger, with 14,668,724 indexed records.
Why the difference? According to Mike More, who leads TONI, the OGS website includes records that were incorporated with permission from other sites. While OGS can host these records, they don’t have the rights to share them on platforms like Ancestry.
What You’ll Find
The index draws from diverse sources including birth, marriage, and death records, newspapers, censuses, government documents, and family histories. Entries typically include the individual’s name, county and township, record type, year, and repository location.
While the collection doesn’t contain images of original records, it serves as a crucial finding aid, pointing researchers toward the repositories where original documents can be accessed.
A Practical Approach
For researchers, searching this might mean a two-step strategy. Start with a familiar Ancestry search. If you don’t find what you’re looking for, check the OGS website directly, as additional records may fill in the gaps.
