Horsburgh

I am looking for a John Herbert HORSBURGH born about 1851 at Edinburgh Scotland. John went to New Zealand date unknown.
He worked on the engines of flax mills in and around the South Island of New Zealand.
He Married Isabella McCloskey in 1877 at Milton New Zealand. They had several children, Annie, William, Isabella, Mary, Elizabeth, Myra.
John may have had a sister named Annie.
John died 1928 at Invercargill New Zealand.
Can anyone help with this search for Johns parents and siblings.
regards
