Dale, I found a Jane Esry, in the 1851 Ontario Census.She is a widow, age 48, in Southwold Township, Elgin County,Ontario.
Jane Meek married James Mitchell, he died. Then I think she married a man named Whitcomb, he died.There is a widow Jane Whitcomb in the 1842 Ontario census. Then she married the man named Essery / Esry sometime after 1842. He died before 1851.
Does this additional information help identify who was the man named Essery that "Typhoid Jane" married?
