As we know Field Jefferson moved to Lunenburg County, Virginia, but I do not have the exact date. Lunenberg County was formed in 1746. He owned land near the Roanoke River. The area of land in which Field Jefferson lived was later Mecklenburg County. Mecklenburg County was formed in the year of Field's death in 1765. As we know, he married Frances Robertson in 1732 and they had eight children. The Children's names were Thomas born in 1733, Peterfield in 1735, Elizabeth in 1736, Frances in 1738,George in 1739, Mary in 1740, Judith in 1741, John Robertson in 1742 and Phoebe in 1743. His wife Frances and the mother of all of his children died in 1750 at the age of 44.
Field owned a large farm which some say he called Occoneechee after the Indian Tribe that had inhabited the area. During his life in Lunenburg County, Field ran a Ferry on the Roanoke River which was sometimes called the "Church" Ferry. It was located near the church and on Sundays the Ferry was free to ride. He also served as a Sheriff, a list taker for Tithes, and a vestryman for Lunenberg County.
Three years after the death of his first wife, he married again. He was married to Mary Hunt Ming Allen, widow, on October 31, 1753. They signed a prenuptial agreement before marrying in which they agreed that all his positions would go to his children at the time of his death and not to her.
He died on February 16, 1765 and he is buried at Saint James Episcopal Church in Boydton, Virginia.
