William Jr. emigrated 1872 as per the 1901 and 1911 Canadian Censuses, making Andrew abt 12. But William Jr. had a legitimate son John Barron Spence abt June 5, 1860 in Ireland.
When William Jr. died in 1920, the death certificate has his father as Ivan Spence (as best I can tell). I did see a record before with his father as William I. Spence but I thought perhaps the J had been mistakenly read as an I - now I have to rethink that.
