This brick was once part of a chimney in a cottage built for Tamati Waka Nene at Russell/Kororareka.For the last decade or so I've been researching brickmaking in NSW - I got on to this because an unsourced remark in a book on trades in NZ referred to Samuel Marsden training young Maori men in brickmaking at Parramatta ca.1819. Much pottering about led me to Tully Mathews, a convict from Louth, who worked for the CMS at Oihi or Rangihoua making bricks in 1816.
There was a Terry Mathews of Glebe who died in 1847 who may have been the same man.
The brick research fed into a friend and mentor's Samuel Marsden biography which was discussed today on Chris Laidlaw's Sunday Morning show on Radio New Zealand:
