The Death certificate says he was 60 years in NZ, and died at the age of 70, his parents were John Andrews and Martha Andrews(Galbraith), it said he came from Johnson Scotland?, maybe they meant Johnstone, either way its a mystery. I don't have his marriage cert yet.
Just throwing these in the "pot" too.

(Extracted) entries from the IGI (familysearch.org) :

Parents - John ANDREWS and Mary MILLAR
and
Daniel Craig Miller ANDREWSb. 18 February 1873

Parents - John ANDREWS and Mary MILLER
So ... are these the brother and sister of John ANDREWS (father of "your" Daniel)

[Couldn't find a birth or marriage entry for John ANDREWS.]
