Hi Tom, Bathgate was one of eight parishes covered by the Linlithgow Poorhouse. I had a chat with Terry (big nanook) and his trusty guidedog Usher via email last night and his thoughts are that though Daniel died in the poorhouse, he was brought home for burial and for that Russell Street Bathgate was given for his address. He had been living there with one of his daughter's. Several other relatives lived on the same street.
My puzzle now is just who was John McLaughlan and why did Daniel use Clifford as a surname his whole life yet someone knew to put McClaughlan on this death cert. Was there even a John McLaughlan or was this name given because of the stigma of the poorhouse.
On his son's (my 3xG grandfather) death cert his father is registered as Clifford and he is Clifford on every census from 1841 to 1881.
I have yet to find a marriage for a John McLaughlan to Helen Clifford but I think it will be in Ireland as that is where Daniel was born according to every census. That could be anytime between 1805 and 1815 according to the various ages given. In 1881 he is 75 and by his death 9 years later had only aged 5 years.
