Hello Again! Within the last half an hour I have managed to find out some more information on the above! His father was definitely DANIEL O'BRIEN though of course he second name spelling alters from census to census. He was born about 1811 in Ireland - I have found both DANIEL and his wife CATHERINE also born about 1811/12 on the 1851 census for GLAMORGAN WALES. At the time he was a dock worker. Living with them is JOHN, their son aged 13, a Mason's Labourer and their other son, CHARLES, aged 4 also born in Ireland. Also residing with them recorded as a VISITOR is JEREMY or perhaps JOSEPH (?) married aged 35 (born about 1816) a BLACKSMITH with his son JOHN born Ireland aged 12 also a Mason's Labourer. I'm guessing that JEREMY could be Daniel's brother. Any pointers or information would be very gratefully received! Happy New Year, Julie Blackman
