My husband is descended from a Thomas Penfold. I have some, but not a lot, of information about him. Seems he was transported to Australia on the John Barry and had to get special permission from the Governor to marry Elizabeth Taylor in 1844. Elizabeth and her children were in NZ about 1863-4. I have no record of Thomas ever having been in NZ. Thomas and Elizabeth had 6 surviving children all born in Australia. Could this be your Thomas?
