But ended up as the chief hard hat diver in the navy, all before ww1,also dived on the building of the Panama cannel, and was in the British Naval brigade in the Boxer up rising and retired back to NZ ware he became the hard hat diver or the Auckand habour board, one very hard man !.. With a current day ralitive now the diver for the A.H.B....grand farther was only 5ft 4in but built like a brick out house ,again he was a VERY HARD MAN....as a wee boy I can still remember the full rig.,sailing ship tatooed across his chest , white hair, looked as if it was comming out of the fog........ he! he! anyway enough of the family tales..
