I am Jack Leigh's son. His mother was Ethel Carey, daughter of Mat jr. Her sister, Laurel (known as Loll) wrote a story in The New Zealand School Journal about 30 years ago about Mathew Carey sr and family escaping from their frontier home during a Maori uprising and moving to Patea, where Mat jr and family remained, although Mat sr returned to Melbourne. I have a recording, obtained from the Radio New Zealand Archives, in which Mathew Carey jr and a friend, Harry Locker, were interviewed in 1945 as very old men, about the early days of Patea.
