yes , that was my thinking when I read he was a wharf labourer.although Catherine , his wife is listed in the electoral role and Wises directory there is never any mention of William , not even on the electoral roles.Maybe becuase he was always at seaThere are other William Arnolds in Nelson but these are a different family again.my William was born in Cheshire England and married in Nelson in 1860 , they had about 6 children so he must have been there some of the time.I have ordered the death cert, for the one who died in Wellington 1902 and hope it may shed some light on whether or not it is the right one.
