I have a Catherine Hourihan who arrived in Pt Adelaide, South Australia on the 6 Jun 1882 aboard the CLYDE. There do not appear to be any other HOURIHAN'S aboard; she would have been 18 years old, as she was born in Caheragh, Skibberdeen 7 Feb 1864, daughter of Timothy Hourihan (born about 1838) and Elizabeth Attridge. There was one other known child - a son Timothy born 16 May 1868, but I do not know what became of him or if there were other siblings.
Does anyone have this branch in their tree? It seems we must all be related.
