He married grannie Eleanora  Schlothauer Slater on 6/3/1920 in Blythswood Glasgow. They had three children. Sara Duncan, William Duncan and Alexander Duncan…my father was Alexander Duncan… Uncle William (Willy/Billy) married Catherine Gallagher (Aunt Rena) aunt Sara married George Marshall.  I hope this information helps you with any searches you might be able to carry out … many thanks for any information you might be able to help with ….
