Golden Genealogy

I am researching the Golden, Daly, Keating,Barry, genealogy all from Cork, Ireland. Also Katherine Coughlin nee Golden, who went to live in Treforest, Pontyprydd, Wales in 1902, Katherine married Maurice Coughlin in Grenagh, County Cork just before emigrating to Wales in 1902. In the welsh Census 1911, Maurice and herself have 5 children, and her brother David is a boarder on Census night. He is 31 years old and Katherine is 35 years old any help with them coming forward from 1911.
