Steve, Not without knowing his age on either a census or his death, neither of which I have been able to find. I used an educated guess based on the christian names of his children, ie, Colin & Margaret & that he was similar in age to his wife. Did they stay in Scotland or did they emigrate? Unless the name was misspelt on the census, I cannot find any record of them in 1841 or any death record for Duncan. I also tried searching for Murray McLaren...... No trace of him in Scotland after his birth.
