My family are from Aberdeen and after doing a little bit of vanity googling, I discovered this page:

It appears that Thomas Kilgour died in or before 1713 as in British Clockmakers & Watchmakers Apprentice Records 1710- 1810 there is an entry for Thomas Kilgour (deceased), Inverness, recording that his son John was apprenticed to Andrew Jaffrey, Burgess & Merchant, Aberdeen 5 April 1713.
Also this page.
Early records are lost, but it is known that the congregation existed in 1716 when Andrew Jaffrey, formerly parish minister of Alford, became minister of this congregation
