Just heard back from David's Irish family. He has a middle name of Adgey he was born September 24, 1897. They believe Samuel stayed in Montreal. There are no other records of him he lived at 98 Le Claire and 3000 Notre Dame east in Montreal. They were told that David may have died in Victoria in 1980 his brother Alexander died in Vancouver in 1979. Two of his other brother Joseph and William both moved to Detroit and worked in the auto industry.
Hope this is helpful
Thanks in Advance
