Rome apple
The story is given that in 1817 Joel Gillet (also spelled "Gillett" or "Gillette" by his descendants) found a seedling tree in a shipment from a nursery. His son planted the tree on the banks of the Ohio River in Rome Township near Proctorville, Ohio where several years later it was found producing red fruit. His cousin, Horatio Nelson Gillett took cuttings and started a nursery to promote the apple. Originally known as 'Gillett's Seedling', it was renamed the 'Rome Beauty' in 1832 in honor of the township. The original tree survived into the 1850s until it was felled by erosion of the river bank.
