View of graveyard
I spotted this cemetery from the road during a recent drive through the Lafayette County countryside, and my husband obligingly stopped so I could take pictures. It obviously is a family cemetery plot, and based on the names on the tombstones the plot appeared to belong to the Jones and Williams families.
William J. Jones was the oldest person buried there, born September 13, 1802, and his wife Angelina was born August 27, 1809. From the research I've done, William and Angelina owned a fairly large plantation near the community of Taylor in southern Lafayette County. They were born in North Carolina but lived in Tennessee just prior to moving to Mississippi. The 1860 Federal Census indicates that William owned real estate worth $25,000 and had a personal estate worth $45,000. The personal estate was comprised primarily of slaves as the 1860 Federal Slave Schedule indicated ownership of 40 slaves with his son Louis owning 20 slaves.
With such an estate and with several children, I expected to find a lot of information on the Jones family, but actually not much turned up. This was puzzling until I dug a bit more.

Records show that William enlisted in Company G, 1st Miss. Infantry in 1861 and served for the duration of the war. As you can tell from the 1870 census, William's land lost much of its value. Both he and Angelina died not long after the census, William in 1871 and Angelina in 1873. No record is found after 1860 for son Edmond so I believe he probably died during the Civil War.

What a tragic turn this family took in the following years. In addition to the deaths noted above, Louis and Helen's son David also died, in addition to several of David's children. His mother Helen's tombstone was inscribed, "Tell Davie, and Willie, to meet me in Heaven." I suppose Louis had the tombstone inscribed thus. When his son William H. died in early 1901, the following inscription was put on his tombstone by his father, "When you died my son, my last earthly prop was removed." Louis himself died just weeks later.
The 1900 census includes a household for Louis B. Jones, a farmer, living with his 29 year old unmarried son, William H., and three servants, including one servant born in England. His location was the village of Taylor. As noted, both Louis and his son died in 1901. Louis's daughter-in-law, his son David's widow, had several small children in her household in 1900. So there may be some Jones descendants out there today.
It appears that this family was wiped out one at a time, from various causes throughout the years, and instead of dozens of descendants, William J. Jones has but a few. Only these graves remain to tell the story of this family. No house remains, no other sign of their existence.
