The city of Sundown developed on land that was once part of the C.C. Slaughter Ranch. In 1931, Slaughter’s son Bob gave property for the creation of a burial ground, and the site has served as the City of Sundown Cemetery since that time. The first marked grave is that of Winne Dell Hines Simmons (d. April 1933). In 1962, the Sundown Garden Club and Sundown Volunteer Fire Department planted trees around the perimeter of the original section of the cemetery, which has been expanded over the years. As evidence of the city’s oil boom period, many graves are those of oil field workers. Historic Texas Cemetery - 2006
