If you'd like to follow-up on Charles Lucas who stayed with John Peyton, perhaps this will help. The Adventures of My Grandfather, a book by John Lewis Peyton (you can find the e-book on line through Google and read for free) tells of the John Rowzee Peyton and Charles Lucas. Lucas was Peyton's manservant, a Jamaican, whose father was thought to be English and mother a native Maroon or Indian, with family and relatives in the Chotank settlement of Virginia. It appears from my follow-up that the Peyton's were in the King Co. area of VA. Children of this Charles Lucas included Charles Lucas Junior who died in 1850 and a daughter, Sarah Lucas Craig who died in 1865. I've written to the Peyton Society of VA, but rec'd no add'l information. Best of luck and please share if you learn more!
