Hi Peter. Have you come across the letter that James Mackison (at Miln of Killbryde, in the parish of Dunblane, Perthshire) wrote to George Washington, President of the United States, in 1795 regarding the whereabouts of his brother in law, John Abercrombie (born in Throsk, parish of St Ninians, Stirlingshire)? See attached.
It is an interesting document for all sorts of reasons but from a family history point of view it tells us that this is probably the James Mackieson ‘in Dunblane’ who married Catherine Abercrombie in St. Ninians in 1777.
The baptisms of seven children are recorded in the Dunblane parish register that name James Mackison at Miln of Kilbryde as the father.
1778 John, 1781 Beatrice, 1783 William, 1787 Helen, 1789 James, 1792 Colin, 1794 George
(Unfortunately, the mother’s name is not given in the baptismal records during this period). It would be a reasonable assumption that Catherine Abercrombie is James’ wife and the mother of these children.
This George Mackison baptised in Dunblane in 1794 is probably the George who married Mary Jack of Muthill in Dunblane in 1814.
