Dee Peters' great-grandmother Matilda Tovey probably made the right decision back in April of 1912.
Her young son, Jack, had suddenly come down with an illness just before the family was to leave for Canada.
Given the sick lad's condition, the prospect of a weeklong sea journey across the Atlantic in third-class was enough for the Toveys to postpone their trip and take the next ship out.
A few days later, they learned that Jack's illness had saved their lives.
"They were all ready to get on the Titanic," says Peters. [Link]
