I've got a Burrell J. Riddick who married Penelope Bright, daughter of Joseph and Mary Tooley Tiggs. The only RI connection I have is a Col. William Pendleton and his son Benjamin from Westerly RI. Benjamin's son Thadius Pendleton had a daugther, Sarah who married John Thomas Stokes. They lived in Pasquotank Co. NC.
I haven't found any native ancestry yet. Mostly folks who came to Eastern NC/VA/MD in the 1600's/1700's.
