...... doing similar study re neighbouring parish of Kildrummy, and are researching, amongst others, two Scott families originating from Cabrach :
Alexander Scott/Mary Robertson - children so far Ann (1777) + Alexander (1778) + David (1789), and
James Scott/Jean Forbes - children found so far (Elizabeth (1779) + Alexander (1785) + James (1787).......
Before answering your query, if you are responsible for the Kildrummyfamiles website then congratulations on a very nice job. My own interest in the Cabrach started through my father who was born at Mill of Kildrummy. His grandparents were George Duncan and Ann Coutts who had the mill and were both descended from Alexander Duncan b at Drywells, Cabrach in Feb 1788.
The Scotts have been in Cabrach from at least the mid-C17th, traditionally associated with Aldunie in the Upper Cabrach. The first mention I have found is of a John Scot at Aldeunie who was one of a group of 12 parishioners who appeared before the Alford presbytery in 1673 to complain about their minister.
I have been unable to work out who were the parents of James Scott/Jean Forbes. None of their 3 known children were in the babtismal register, but they all appear at Aldunie in the censuses. 2 children James & Elizabeth never married and they lived together until Elizabeth's death 7th Nov 1858. James died a pauper 24 Jul 1867. Both deaths were at Aldunie. The other son Alexander also lived at Aldunie from 1823 to 1871, and previously at Hillock. He married Isobel Stephen of Huntly in 1813 and had 9 children in Cabrach.
Alexander Scott b25 Sep 1748 at Aldunie, husband of Mary Robertson was one of 4 children born at Aldunie to Alexander Scott and Anna Hen(d)ry. Alexander sr is known to be the son of John Scot, probably the one mentioned in 1673. Mary Robertson's children were :
1:Ann Scott who married William Ronald 1803 - their son James married Janet Scott daur of Isobel Stephen above.
2:Alexander Scott who married 1806 Jean Forbes dr of William Forbes & Jean Laird
3: David Scott who married 1816 Elspet Seivright.
I have attached descendants reports for these people. My own Scott ancestor in the Cabrach was Isabel Scott who married James Ferrior in 1764. She had various Aldunie Scotts as baptismal witnesses for her children.
