The Mount Vernon Plantation (the name was later changed to Pickney Hills) was located in Jefferson County about seven miles east of Monticello, Florida with a view overlooking "Razor Lake," so named by Mr. Hollingsworth because of its shape. The number of enslaved peoples listed, the livestock listed, records of sales of farm products, purchases of supplies, and descriptions of different parcels of land shown in the Last Will of John Hollingsworth indicate that Mount Vernon Plantation covered rather extensive acreage. The will also shows that he owned a home near Edgefield, South Carolina, which was situated on "about eleven hundred acres."
