He had four siblings, two sisters and two brothers, that we know of. It appears that only one of them, his sister Hannah, lived to adulthood. His siblings were as follows:
He also had a younger half-brother who died in infancy:
Sometime about 1840, James moved with his mother and father from Montreal to Yorkville, Ontario. Yorkville is now almost in the heart of downtown Toronto but was then a prosperous village a few miles north of Toronto’s city limits.
He married an Irish girl named Margaret Ann Quinn in Toronto on March 26, 1856. They were both eighteen.
They would have ten children, although there is some doubt about whether the first, Martha, was actually theirs. Assuming she was, though, James and Margaret’s children were as follows:
- Martha Warner
- William James Warner
- Robert John Warner
- Hannah Maria Warner
- Thomas Benson “Tom” Warner
- Elizabeth “Daisy” Warner
- Sarah “Sadie” Warner
- Edward Warner
- Ella Warner
- Harold Rix “Harry” Warner
James worked all his life in the printing business. For most of that time he was “compositor” (what we would call a typesetter).
He died in Toronto on January 29, 1909, at the age of 71, and was buried in Toronto Necropolis Cemetery.
