Prairie Grove Cemetery served residents of the Aleo community from the late 1800s until the middle of the 20th century. It has ties to Prairie Grove Baptist Church, which set aside land for burials. The oldest known grave dates to 1895. World War II hero Audie Murphy lived in the area for a time, and his mother and grandparents are buried there. Victims of the 1927 tornado that came through nearby Nevada are also interred there. As a vestige of 19th-century rural settlement, the cemetery remains a reminder of the pioneer community of Aleo.
