The Sadler Family Pioneer Home, at 5262 Eastern Valley Road in McCalla, is the oldest home in the area and was built by John Loveless, a settler from South Carolina. It is believed to have been originally constructed as a "single pen" log cabin (a square pen made of logs), between 1817 and 1820 upon a small parcel of land. After Loveless died sometime in the 1830s, his widow, Martha Daniel Loveless, sold the two-story clapboard home to Isaac Wellington and Martha Prude Sadler, who were from North Carolina. Soon thereafter, Sadler expanded the home into a substantial "I-house" residence with shed rooms to the sides of a dog trot, two stories covered in weatherboarding, and four chimneys, although only three remain. An influential planter who owned 2,800 acres of farmland and 43 enslaved persons, Sadler helped found the nearby Pleasant Hill Academy and the Pleasant Hill Methodist Church; he also built the first sawmill in the area. During the American Civil War, one of Isaac Sadler's sons died fighting for the Confederate Army. When U.S. Army general James H. Wilson led a raid through Alabama and Georgia in 1865, the nearby Tannehill Ironworks was destroyed but the Sadler home was spared. The building remained in the Sadler family until the early 1970s, when one of the descendants donated it to the WJCHS.
Construction on the nearby Owen Plantation House, at 1740 Eastern Valley Road in Bessemer, began in 1833, when settler Thomas Hennington Owen built a two-room home for himself and his wife Malissa Rose Sadler, sister of Isaac Wellington Sadler. In 1838, Owen expanded the modest home into a two-story "dog-trot" style building made from hand-hewn logs and lumber gathered from the surrounding 1,000 acres of property. The home features a gabled roof and a porch with a half-hipped roof, supported by eight columns, that was originally covered by wooden shingles but were replaced with metal. A prosperous planter and merchant, Thomas H. Owen also co-owned the nearby Williams & Owen Forge at Tannehill, which was in operation from 1861 to 1866 when it was destroyed by a flood. When Wilson and his troops made their way through the area in 1865, Owen's home was ransacked and his grain buildings burned to the ground. Owen served as county commissioner in the 1870s. After his death, the home remained in the Owen family until the 1970s, when they donated it to the WJCHS.

The maintenance of these three historic homes is managed by the WJCHS. Originally formed in 1973, the society raises money to maintain and restore the homes as well as educate the public about their architectural and historical significance through lectures, artistic and cultural demonstrations, and tours. Yearly events include the Annual Heritage Holiday Tour, the Rustically Regal Holiday Home Tour, and Ghost Storytelling. Adjacent to the McAdory Plantation House is the Watercress Darter National Wildlife Refuge, created to protect this endangered and endemic species. Also nearby are the Tannehill Ironworks Historical State Park to the south, the Robert Trent Jones Golf Course at Oxmoor Valley to the north, and to the east, Oak Mountain State Park.
