Moses Carver purchased a total of 240 acres (0.97 km2) in Marion Township, Newton County, Missouri.
As an early settler in the area, Carver selected a good site with an abundant water supply.
Moses needed help as the farm prospered and in 1855, he purchased Mary, an enslaved thirteen-year-old girl, from a neighbor.
At age 96, he decided that he was no longer able to farm so he went to Galena, Kansas to live with his nephew, John Carver, on Shoal Creek.
The Association later donated the land to the National Park Service, making the 240-acre Moses Carver Farm property complete.
