Locust Grove State Historic Site, Protected historic cemetery in St. Francisville, Louisiana.

Locust Grove State Historic Site protects the cemetery of the former Locust Grove Plantation near St. Francisville, West Feliciana Parish, Louisiana. The grounds lie at about 54 metres above sea level in rolling, wooded country. The graveyard holds the marked graves of Sarah Knox Taylor Davis and General Eleazer Wheelock Ripley.

Locust Grove Plantation belonged to the family of Anna E. Davis Smith, sister of Confederate president Jefferson Davis. The cemetery holds Sarah Knox Taylor Davis, daughter of General Zachary Taylor and first wife of Jefferson Davis, who died in 1835, and General Eleazer Wheelock Ripley of the War of 1812. In 1937 the heirs of Anna E. Davis Smith deeded the cemetery to the Office of State Parks.

The cemetery belongs to the former Locust Grove Plantation, once owned by the family of Anna E. Davis Smith, sister of Confederate President Jefferson Davis. Her heirs deeded the burial ground to the Office of State Parks in 1937, which is why it is now a state historic site rather than a private family plot.

The cemetery lies near St. Francisville in West Feliciana Parish, about 11 km west of Jackson, at roughly 54 m above sea level. It is a small burial ground reached by road; the surrounding land is wooded and receives about 2,000 mm of rain a year. Plan a daytime visit and confirm access with the Office of State Parks, which has held the cemetery since 1937.

Sarah Knox Taylor Davis, daughter of General Zachary Taylor and first wife of Jefferson Davis, died of malaria in 1835, three months after their wedding, and is buried here. General Eleazer Wheelock Ripley, a War of 1812 commander, lies in the same cemetery.
