William MOFFAT -m- Agnes WATSON and sons William -b- abt 1843 and James. Both sons
were in Glasgow by the 1871 Census, but James' age is indecipherable. It could be 28,
meaning he was about the same age as William, or 18, meaning he was much younger.
There are no clues about where they lived in Ireland or the names of any siblings. I
don't have much to go on, except the Glasgow Census information which states they were
born in Ireland, and even then James sometimes stated he was born in Glasgow. When each
of them died the parents information was the same: "William MOFFAT Farmer deceased
and Agnes MOFFAT MS WATSON deceased"
