Henry William Wiliams

Good Day All

I am searching for a Welsh settler named Henry William Williams. I cannot find any records of him apart from his children's and wife's death notices as well as baptismal entries of his children. His first child, presumably, was born on 28 September 1856 to a wife Elizabeth. In 1874 he seems to have a child with a wife named Cornelia Susanna. On Cornelia's death notice it says that he died about 1886. Apart from that I can't find any more information about him and have tried looking at ship records for before 1856 for a Henry William Williams but have been unsuccessful thus far. I would appreciate it if anybody has any further information or could assist with their research skills.

Thank you
