Martha Cawze / Old Cheraw - Question

The Cheraw Preserve was a set-aside for survivors of the Cheraw ("She-Raw) tribe. It was also a town in South Carolina, Chesterfield County, on the PeDee River. Her Father may have been Richard Casey. So, difficult to tell. She married William Sweat/Pamunkey (mother a Pamunkey-like Pocahontas- Indian), the son of Robert Cornish Sweat, the love-child of Robert 'the elder' Sweatt and Margaret Cornish, one of the first 20 slaves sold in Jamestown (they were found out, he did penance, she got 30 lashes), and remained a 'servant' (they weren't called slaves yet). It seems the Sweatt family lived in some version of the swamp for the next 200 years (until my great-grandfather Leander moved to Naylor, Georgia). Martha's son, William, 1732, married Lucy Turbeville, whose mother, Sarah(Jones) was counted in the Westron (western shore of the river) Indian censused community. Henry (Sweet) Clifford

Are any of the Sweat family descendants members of the Pamunkey today?
