I don't think there are any records that name "Littleberry Roach" in the 17th century. The first documented man by that name seems to have been born about 1758, had a wife named Mary Cobb and a daughter named Elizabeth. He was a Revolutionary War soldier who served from North Carolina. There is a Littleberry Roach on the 1790 census in South Carolina who may or may not be the same man. The Cherokee were forced out of South Carolina before the Revolutionary War and the town of Tugaloo was abandoned. Another Littleberry Roach was married in Rutherford, North Carolina to Susannah May in 1823. There is a different Littleberry Roach born in Kentucky about 1799 who married Polly Burks in Kentucky in 1827; they are probably the couple on the 1850 census there. I don't find any records for anyone by this name prior to the Revolutionary War soldier. No one lived with or near the Cherokee or Shawnee. There are no "Cornstalks.'' The Shawnee chief by that name had no known wife or children although he is attached to more than one white family on the Internet.
The FamilySearch tree listing these people has no sourcing and makes no sense - it says Littleberry Roach dates 1675-1725 was the husband of a woman who wasn't born until 1740!
The colonial records of New Kent County VA were mostly destroyed; the is no one named "Roach" in any of the surviving records.
Charity Roach Lee, the daughter of John (possibly James) Roach, was born in 1851, died in 1926, lived in Tugaloo, S.C. when she died.
