Thanks again
I have just had a quick look at the website you suggested and will go back now and see what I can digest from it.
There seems to be a lot of information available.
It seems to be that a number of my relatives went to sea in the mid 1800's or at least I am assuming so because I can't find them anywhere else but it is also a struggle to find them at sea!!
Just wish I didn't have quite so many loose ends to tie up.
Thanks again for your help and enjoy New Zealand.
