Hi, are you sure that the name of Thomas Dobbie's wife is Grace? I ask only because I have looked at marriages between 1800-1840 and there is not one recorded for a Thomas Dobbie marrying a Grace. The only marriage of a Thomas Dobbie in Old Kilpatrick/Dunbarton is with a Mary during the above time period. To double check this, I looked up the birth of a Grace Dobbie and found 1 in Dumbarton,Dunbarton but again,the mother is not Grace. Could the name Grace perhaps belong to the mother of either Thomas or his wife? Kim
