John McIntosh Lorimer was born in Glasgow on 3rd March 1920.
His parents were Thomas Ward Lorimer b. 21 Jan 1894 in Aberdeen, died 18th March 1963 in Vancouver, and Mary Dickson McConnell b. 15th March 1893 in Glasgow and died the day after John McIntosh was born.
Thomas and Mary were married in Glasgow on 18th June 1915.
Thomas moved to Vancouver (I believe through Quebec) and married Janet Faulds Cunningham in Vancouver on 28th August 1922.
Thomas's brother, Walter Keir Lorimer, b. 11th October 1890 in Edinburgh, married Mary's sister, Catherine Ritchie McConnell on 24th May 1921 in Vancouver. He died on 21st February 1934, and Catherine subsequently re-married Alexander Anderson. She died on 17th August 1974.
I believe that John McIntosh Lorimer probably went to Canada with his father, but, at the moment, I have no proof.
If anyone has anything that they can add, I'd be delighted to hear.
