The Longoria family were among the initial Spanish settlers to arrive in this region in the mid-1700s. Juan Rosas Longoria and Maria Salome Cano were among the men and women who founded permanent communities such as the Villa de Reynosa, establishing the Longoria family in the area. They and other pioneers introduced ranching into the area with techniques brought from southern Spain, many of which remained in use centuries later. In 1831 Irineo Longoria increased the family landholdings north of the Rio Grande by purchasing portions of the LLano Grande, La Feria and Ojo de Agua land grants. He added these tracts to the land of his second wife, Maria Inez Cavazos. They established residence in the community of Santa Maria. The Longoria ranch stretched from what became Sebastian to the Rio Grande. The family also farmed the land and participated in the early development of irrigation systems in the Rio Grande valley. Juan Miguel Longoria (1815-1875) became the owner of the Longoria ranch in the mid-1800s. Married three times, he was the father of 17 children. His first wife was Soledad Cavazos. His second wife, Silveria Ruiz, became one of the first persons interred here upon her death before 1853. After his death, Juan Miguel's third wife, Teresa Guerra, became the family matriarch and managed the ranch from 1875 to 1909. Juan Miguel's grave is marked by an above-ground brick tomb. By the late 1990s, the cemetery was in a state of disrepair. Longoria descendants organized to restore the site and its estimated 371 graves to ensure the endurance of the Longoria Cemetery as a chronicle of the diverse history and heritage of Texas. (2000)
