Known over time as Brother's Lot, Wilton Farm, Greenway Farm, Allenwood Farm, and Swan Harbor, this farm began in 1659 when Colonel Nathaniel Utie received a land grant from Lord Baltimore for a large tract in the area. Generations of the Giles family lived and worked the land during the 1700s. In 1797, John Adlum purchased the farm; he had served in the Revolutionary War, worked as a surveyor and judge in Pennsylvania, and was one of the foremost horticulturists of the Colonial period, specializing in native wine grape vines. In 1809, Adlum sent a bottle of his Burgundy to Thomas Jefferson, who was so impressed that he bought 165 cuttings from the farm's vines to plant at Monticello. Many years and many families later, W. John Kenney purchased the farm in 1951 as a summer home and added a pool, tennis courts, boathouse, greenhouse, larger kitchen, and formal dining room. He donated the property to Johns Hopkins University in 1986, and Harford County purchased it in 1994. Swan Harbor Farm is now a Harford County park on 931 acres along the shores of the Upper Chesapeake Bay, with the house and grounds rented for weddings and conferences, county programs and festivals held there, birdlife including black ducks, Canada geese, and wood ducks observed at the waterfowl pond and bay pier, and the Maryland Agricultural Education Foundation headquartered at the Amoss Agricultural Center to educate teachers and students about the important role of apiculture in their lives.
