John Morrison was likely born on 2 December 1919 in Blantyre to John and Rose (McGuinness) Morrison. He married Henrietta Paterson in 1943 in Blantyre. The couple had four children. According to his granddaughter, John Morrison died in 1982 in Carluke. I can find no supporting index entry on ScotlandsPeople. However, this does not mean it does not exist.
