We (Ambrose McKee researchers) had seen the 3451 reference for years and last year, Neal Freeman, also a descendant of Ambrose McKee, through his membership in the SAR was able to work with the NC Society of Founders and Patriots, Salisbury NC Governor Grady Hall to obtain an actual copy of the document in question.
Wonderfully preserved, a small scrap of paper says:
