In my DAVIS line, I have Swearingen surname only [so far] from your list. I have two sources that Lydia Swearingen (b.1726) married Charles Davis. I have sources of Lucy Davis marrying Van Swearingen. Lucy is supposed to be a dau. of William Davis and Mary Duvall. There are many family trees with John and Mary (Ray) Swearingen that are more complete than mine, so I am sure you can find information there.
