I, too, am a descendant of David Burnes and his wife, the widow Anne Fleming. I have quite alot of info about David and Anne's children and descendants, but need to find out where David was born. Their grandson, David Burnes II, was the one that had the dealings with George Washington, I have copies of many of the letters between them, as well as estate papers that I would be happy to share. David II is definitely said to be "Scot" but we have no idea where his grandfather came from, or when. Very frustrating!
Would love to share info with you!
