From Ancestry.ca:
1916 Census, 543 Ellice Avenue, Winnipeg
REARDON John, head, age 31, born England, immigrated in 1910, Lineman, CNR
Catherine, wife, age 26, born England, immigrated in 1910
John and Catherine were married in 1910 but had no children on the 1916 census.
It’s sad, but one or both of these could have been their sons, from MB Vital Statistics:
REARDON John, died 4 July 1913, Winnipeg, age 1
REARDON Leonard Milton, died 26 Aug 1913, Winnipeg, age 7 months
Manitoba death certificates cost $12.00 each and have parents’ names, cause of death, place of burial, etc.
I haven’t been able to find John and Catherine on the 1911 census but it’s free to search here:
