We now have a signature of Christopher Pryor of Gloucester County, VA. He signed a 1787 legislative petition concerning the taxation of slaves.
And an earlier signature from 1786. I noticed that he signed near John Whiting on both petitions. (see post that explores Whiting connection)
And yet another signature from 1785 and again near John Whiting. Under Whiting is James Baytop– Col Thomas Baytop was master of Botetourt Masonic Lodge and the executor of Christopher Pryor’s estate.
