John Pendleton's son by Sarah Madison, was James Pendleton, and was born at Port Conway in 1751. He married Mary Ann Phipps and moved to Kentucky. They had a daughter Esther who was born about 1794. They also had a son, named Thomas Madison Pendleton, born in 1791. By deduction I have always assumed that Sarah Madison was the daughter of a Thomas Madison, and James named his son after him.The only question is which Thomas was Sarah;s Father.
