My source is from a book. "The Normans of Normandy Hall" written by Dr. Lois Norman in 1971.His sources are various records from Virginia and North Carolina.Here is what is written in the book:
"Jared Ellison Groce married Sarah Sheppard in 1767; she was the daughter of James and Lucy Sheppard of NC. Her brothers were Jacob, William, James, John and Henry; her sisters were Elizabeth, Mary and Martha.This Sheppard family came to NC from Halifax County, VA.Sarah was born about 1752. She was not mentioned in her husband's will of 2 March 1803, thus it must be assumed that she died before that date."
I am in the process of receiving the entire book, wo when I receive it, I will look in the references to see where the information came from.Dr. Norman was a meticulous researcher.
