On marriage of son, Henry Tyo,32,b about 1880,married 1912, mother's name is given as Esther Rochford.
There are 2 Joseph Tyos in Glengarry and both of their wive's names are Esther. Makes for some confusion!
Anyway, the 1881 census information that I gave you - on checking some of the children's birth registrations, mother's name was Esther Murphy so this family isn't yours.
I cannot see any birth registrations for children of Joseph and Esther Rochford/Rushford. Only the marriage for Henry.
Have you looked for a death registration for her? It may have parents on it.
