Hello, Looking for the ancestors of James Joseph O'Brien. His father was William O'Brien, Engine Driver, born c 1820s. Lived in Dublin. His wife is Mary O'Neill. b. c 1820s. there abouts.
Their son, my grandfather, James Joseph O'Brien born 17 March 1888, Dublin. Twin sister, Kathleen.
James came to Australia via Rio de Janeiro married Annie Gertrude Mason in 1915 died in Australia 1926 (aged 38). There was no contact back then with his family to contact them re his death. James was a plumber/gas fitter by trade in Sydney. On his marriage certificate it states he was a mechanic.
Not much to go on. Desperately want some help. Thanking you in anticipation.
