The sidewalk ahead leads to the Johnson Settlement, frontier home of President Johnson's paternal grandparents, Samuel Ealy Johnson, Sr., and Eliza Bunton Johnson. Between 1867 and 1872 Sam Ealy Johnson, Sr., and his brother Tom drove huge herds of longhorns from this homestead north along the Chisholm Trail to Abilene, Kansas. The original cabin remains, surrounded by barns and outbuildings that reflect nearly a century of ranching and farming on this land.
