Discrepancy
In 1842 President John Tyler bought "Walnut Grove" from Collier Minge, his cousin and a local planter, and renamed the plantation "Sherwood Forest," as he likened himself to the story of Robin Hood regarding the Whig party. According to the official website, sherwoodforest.org, there is no mention of Harrison's ownership of the plantation. Also factually noted, Harrison died the year before Tyler, who was his Vice President for only one month, purchased the plantation.
William Henry Harrison received a land parcel from his older sister Elizabeth Harrison Rickman Edmondson after her death in 1791. The parcel had been purchased from Thomas Brown by Dr. William Rickman of Millford (now Kittiewan Plantation), Elizabeth's husband before 1781. When William Henry Harrison sold this parcel to his brother Carter Bassett Harrison in the mid-1790s, the parcel was referred to as Brown's Quarter, which was the same name given to the parcel on which some of Sherwood Forest now lies. However, it was simply Brown's land, but not Brown's Quarter, and not part of what is now known as Sherwood Forest.
