If James Duffy b. ca. 1831 in the 1881 census is the correct one, then there was James Duffy b. Charlottetown 8NOV1831, bpt. the same day by Father B. D. McDonald in St. Dunstan's Basilica. He was the s/o Patrick and Sally (Steward) Duffy. Baptisms the same day are a bit unusual and suggests fears that the child may soon die.
