According to our research, the 119 acres at 500 Hibernia Road was part of an 1820 acre land grant from William Penn to George Claypoole in 1714. Old maps mark it at the center of an Indian / Native American Settlement, almost certainly the Lenni Lenape, as they retained one mile east and west along the West Brandywine Creek in a 1706 agreement with Penn, though the agreement was not honored by Penn's heirs. In 1793, it was acquired by Samuel Downing, for whom Downingtown is named, and later, Charles Brooke. The Hibernia Estate at Hibernia Park, including the iron forge, and the former property of George Harrison, a colonial weaver, were all part of Downing's estate. Much of the land has been protected, but this plot was purchased at auction in 2008 by an LLC. Now, in 2026, the owner reached an agreement with Toll Brothers to sell the property for development. Toll Brothers application has packed 237 age-restricted homes onto 119 acres of farmland, wetlands, and two streams that merge to feed into the Brandywine River water supply.
