Established in 1878, Armour Cemetery served the former community of Armour on property deeded by founder James Armour for school, church, and burial purposes. Born in 1825 in Jackson County, Georgia, James Armour was a landowner, community and church leader, and Civil War veteran who married Narita Jane Kennedy in 1849 and had ten children. In 1882 he laid out the community of Sandy Creek, which later bore his name, and by 1884 the settlement, one of the earliest in northern Limestone County, had two churches, a school district, and two gristmills. The community declined quickly after 1903, when the Trinity and Brazos Valley Railroad established Coolidge one mile north, drawing businesses and institutions including Sandy Creek Baptist Church, now First Baptist Church of Coolidge. The oldest marked graves are those of Annie Lou Hooper and her husband, James E. Hooper, both of whom died in 1878. Also buried here are community leaders, area pioneers, and veterans of military conflicts dating to the Civil War. Features include vertical stones, curbing, and fraternal monuments. The cemetery is divided into four sections: Old Armour, New Armour, the Norwegian Cemetery, and the Catholic Cemetery, known locally as the Mexican Cemetery. The Coolidge Cemetery Association maintains the first three sections, while descendants care for the Catholic Cemetery. Armour Cemetery is the last remaining vestige of the historic Armour Community and continues to serve descendants of the area's early pioneers.
