Hi
Presumably, John's 1864 marriage record names his mother as Agnes MURRAY deceased, and his father as James McLAREN? And is this matched by information on his death record?
What is both his and his father's occupation recorded as in 1864? And did John give a specific address in 1864?
I've found other information posted on line… some that suggested that John was born abt 1840 in Kirkintollch, Dunbartonshire… and this I see matches the 1871 Census (below). He died August 1898 in Dunedin NZ, recorded age 66 - which indicates a birth of around 1832.
