One of a Kind

To my knowledge, this is the only photograph of my paternal grandmother Mary Jane Baillie/Campbell/Cannon, with her four children, their respective spouses, and her two grandchildren (one of whom is me).

I have no idea what the occasion was, but this photograph was taken some time in 1957, in the living room of my uncle Jack Cannon, my father's half-brother, who is seated at the far left of the picture. To his right is his sister, my father's half-sister, Mary Cannon, who never married. Third from the left is Doug Liddle, who was married to my father's sister Jess Campbell, and next to him is his son Doug, my only cousin on my father's side.
In the middle is my grandmother, who by this time was a widow twice over. To her right is my father's sister Jess, and to her right is Jack's wife Alberta. At the far right is my father William Campbell, and to his left is my mother Claire Elizabeth McLeod. As you might have guessed, I am seated in front of my parents, looking rather bemused by the proceedings.
I have had no contact with my cousin Doug in over forty years, and as far as I know, with the exception of my mother and he and I, all the others pictured here have passed away.
