Hello, David Armstrong of Kirtleton is my 5th g. grandfather. He died 11 Nov. 1813 in Dumfries. His father was William Armstrong (1662-Aft. 1724) William was a merchant traveller (or chapman) in South Britain as a younger man. I don't know for certain who William's parents were, but I have some ideas on that.
In 1717 William married Agnes Bell in Dumfries. Agnes (1672-1688) was the daughter of Richard Bell of Blackethouse and Mary Irving.
David was a very interesting guy! We have lots on him, including things that he wrote. He had Kirtleton because his wife Peggy's parents had owned it earlier. I come down from his oldest son William who joined the British Army and settled in New York after the war.
