Harvey, second son of Ben and Olive was born on January 5th 1915 in Toronto, Ontario. When he reached adulthood, he married a girl by the name of Elizabeth. They lived in Toronto for a time, but Harvey worked for Union Gas and eventually moved to Sarnia.
Harvey had the initial "B" which apparently stood for Benjamin. Frances and Ben's first son was named John Benjamin but was either stillborn or died the same day of his birth, so it makes sense that Benjamin would like to have a namesake.
I have just recently been in contact with Harvey's grandson and hopefully will soon be able to fill in some of the blanks.
