Thomas Clagett purchased this tract, 822 acres of Bealls Chance, Green Spring, etc., in equity from the representatives of John E. Berry in 1831.
Along with additional lands acquired at about the same time, Thomas Clagett created two plantations, The Cottage and Strawberry Hill, totaling approximately 1,000 acres.
In addition to farming, Charles Clagett served for twenty years as a judge of the County Orphans Court.
After the death on July 7, 1972 of Charles, who lived and worked in Baltimore as a wealthy lawyer, Navajo was conveyed to the Chesapeake Bay Foundation as a center for environmental education.
The 283-acre (115 ha) working farm, formerly known as Navajo, was bequeathed to the Chesapeake Bay Foundation along with $600,000 in 1981 by the estate of Charles Clagett, who made it clear in his will that he wanted the place used for educational purposes.
