James Henderson Key and Meredith Jane Roark, who married in 1886, came into possession of the parcel at 208 Church Street sometime after their marriage. Meredith Jane was the great-granddaughter of former landowners and early Lafayette and Macon County settlers John B. Johnston and Mary Gresham Johnston. The Keys raised their daughters, Lassie Lynn Key East and Delia Diana Key Beasley Jackson, in this home. After Meredith Jane's death in 1962, Delia and her daughter Virginia Key Gresham Beasley came into possession of the land. Virginia wished for the land and the original Johnston cabin, which had been relocated to the back of the property, to be given to the city of Lafayette for use as a park benefiting the community. After Virginia's death in 1966, Delia carried out that intention, and at her death in 1975 she directed in her will that four acres be converted into a public park named Key Park, to be owned by the City of Lafayette for the use, pleasure, and recreation of its citizens and the citizens of Macon County for all times to come, and she also bequeathed funds for the park and its amenities. In 2004, the city purchased two additional adjoining acres from the heirs of Mary Judith Parker Reagan, allowing more space for larger community events.
