Robert married Isabella McCready on 22 January 1863 at the Knox Church in Dunedin and one of the witnesses to the wedding was Thomas Nidd from Port Chalmers. This would appear to be my Great Great Grandfather, Thomas Nidd and it seems pretty much certain that they were brothers. Robert was a waterman at that time, and both Robert and Isabella also lived in Port Chalmers. Isabella seems to have been born around 1846 in Ireland. She died on 4 February 1890 in Reefton on the West Coast of New Zealand and buried at the Reefton Cemetery.
William John Nidd was born in 1868 at Marsden West Coast, inland from Greymouth.
Elizabeth Nidd was born in 1874 in Reefton but died at the age of just 5 weeks of convulsions.
Robert Nidd Jnr never married.
Together William and Mary Jemima had the following children, but throughout their lives, their name appears to have become evolved from "Nidd" to "Nedd":
William Edward George Nedd was born on 27 January 1893 at Reefton. William Jnr never married and died on 16 June 1955 in Nelson.
Robert Ernest Nedd was born on 29 September 1897 Fern Flat, West Coast. He died on 27 September 1962 at Nelson. Robert never married.
