I have come to a brick wall with tracing my Irwin family tree. My grandad was Henry James Arthur Irwin b. 1885 Kingston Surrey. I have found his father Thomas Irwin in most of the census, but he age differs from time to time and in some he says he was born in Ireland and others he says he was born in Gibralter between 1839 and 1842. At the age of 39 he says his occupation is Army Pensioner. He married Charlotte Amelia Hillyard (nee Watts) in 1881 Kingston Surrey. I just cannot find his birth, nor his parents. I believe he was born in Carrigaline, County Cork, Ireland, but cannot find his birth. Any help would be much appreciated.
