I am a descendant of Elizabeth Briggs b.1780 Rowan Co., NC d. 1855 in Brown Co., IL. You seem to be knowlegable of the Briggs that left NC and moved to Il. Could you please check and see if you have Elizabeth in your file? I have no idea who her parents were, but she married George Summey/Summy. They are my 4th greargrandparents.I have their children and other descedants if you are interested.
