"Daughter of Captain William Bryan, I and Mary Bryan Wife of James Grimes, Sr and William Dent Chinn"
The Chinn marriage is incorrect. Sarah and James Grimes were buried together on the family farm outside of Lexington KY. I have photos of their grave sites.
Sarah m. William Chinn was the daughter of James Bryan, son of Morgan Bryan.
