John Caffrey is on the 1861 census aged 20, living in Sunderland as a boarder. On the 1881 census, he is 40, now married to Ann and still living in Sunderland. He was born in Ireland (nothing more specific I'm afraid). I did once find a marriage entry for a John CAFFRY, but when I received the certificate it was obvious it wasn't the right one. He is not listed on the 1871 census, he died in 1882 ( I have his death certificate).
