Witnesses to marriage were William Boyle and Kate Boyle, both of Bangor. James was a farmer at the time, living in Bangor. They were married by Q. E. Butler.
James, his wife, and 4 sons were all living together in Ameliasburgh township in Ontario in the 1921 census. He, and his 3 eldest sons, are all listed as farmers.
1930 Flint, Michigan census shows him as having emigrated in 1924. Along with his wife and two sons (Armour and Fraser), they had a roomer named Roy J Creel (originally from Mississippi) living with them as well.
Since he and his son Armour died the exact same day, I presume an accident?
