Thomas Ball was a plumber and gas fitter by trade. He was apprenticed in 1891 to Joseph Samuel Shepton in Penarth, Glamorgan, Wales. This is his 1906 National Registration of Plumbers card:
Interestingly, Thomas' card is dated 18 Apr 1906. He left for Canada on 25 May 1906. It makes me wonder when were his plans to emigrate made? I suspect that he needed his plumbers' registration completed before leaving for Canada.
