Ovilla, on upper Red Oak Creek in northern Ellis County, is the oldest town in the county. It began in 1844 as a fortified settlement known as McNamara's to repel Indian incursions. James McNamara arrived in 1843 with his new wife, Joanna (Hale) McNamara as the first Peters Colony settlers of this area for which they received 640 acres that made up the beginning of the locale that was later to be called 'Shiloh' for a nearby creek and a newly formed church. The McNamaras arrived with other Peters colonists: the Billingsleys; Mrs. McNamara's family, the McCommases; and James Sterrett (Mrs. McNamara's brother-in-law, who established Sterrett, Texas). The marriage of James Sterrett to Clarinda (Hale) Squires of 7 July 1844 was the first marriage to be performed within the future boundaries of Ellis County, which was still within old Robertson County at the time. James McNamara served as sergeant in Smith's Company of Texas Mounted Volunteers during the War with Mexico in 1846–1847 along with his brother-in-law, James Sterrett. The little village grew as other Peters Colony settlers arrived in the area to attend brush arbor meetings of the Shiloh Cumberland Presbyterian Church, which was started by Rev. Finis E. King in 1847. James McNamara died in New Orleans on 5 May 1852, and his widow liquefied his assets and left Texas for the gold fields in Tuolumne County, California, with all of her remaining maternal family members.
