Although this appears to be two separate buildings, structurally it comprises the historic C.A. Milam and Son Store, one of the largest mercantile establishments in old-time Glen Rose. Family tradition states that J.R. Milam started this enterprise in 1881, when he built the first phase of this building, a cut limestone structure with 30 feet of street frontage, He later widened it 46 more feet to the right, with matching stonework and big display windows. From inside these walls for eight decades the Milam Family supplied Somervell County residents with a general range of merchandise including groceries, dry goods, wheeled vehicles, harnesses, agricultural tools, and caskets. After Milam’s store closed in 1960, a series of enterprises occupied the space, among them being a White Auto Store selling automotive supplies, household goods, and appliances. It was for this business that the right side of the building was modernized with larger plate glass windows and an aluminum and fiberglass slipcover in 1962. This changed the exterior appearance of the building, but behind the cover the historic structure remains. In the last half century the Milam store building has housed retail merchants and a church.
