I am a distant relative of General Thomas Moonlight from the Scottish side of the family. My grandmother was Marjory Whyte who was the grand daughter of Ann Moonlight (2/07/1800 to 15/04/1882)(Kinnel, Arbroth, Scotland) who had a direct line to the Moonlight family in Arbroath.
Just thought this might be of interest to you.
I am current updating our extended family tree and would welcome any information you may have on the Moonlight family in USA.
Best wishes
David Robb Harris
