Planter Robert Hairston established a home in what became Henry county that he called "
Marrowbone plantation". The plantation house may have been built around 1775–1776, and was passed down to his son George, and remained in the family for the next five generations, until 1881. Other accounts say that Marrowbone plantation was constructed in 1759, in the part of
Pittsylvania County, Virginia, which later became Henry County, and one historian claims the house was built in 1749. Yet another states that when Franklin County was formed, Hairston's
Pigg River home was no longer in Henry County, so Hairston became a member of its first court. On the various farms and holdings the family owned, by the end of the 18th century he also owned nineteen slaves. In 1791, Robert Hairston owned 1,684 acres of land.
