Catholic heritage in Brooks County reaches back to before 1800, as shown by local geographic names. The area belonged to the Diocese of Monterrey until the Diocese of Texas was formed in 1847, and within that new diocese it was part of the Brownsville Parish until its transfer to San Diego in 1866. Fathers Claude Jaillet (1843-1929) and Peter Bard (1846-1920) of San Diego traveled through the area for about 40 years, ministering on scattered ranches. In 1904-05 the Mission of San Ysidro (Saint Isidore) was built in Falfurrias. The Rt. Rev. Paul Joseph Nussbaum, first Bishop of Corpus Christi Diocese, established the Parish of Saint Isidore in 1914. The Chapel of Saints Peter and Paul was built nearby in 1916 for English-speaking communicants. In 1925 the mission was merged with Saint Isidore to form Sacred Heart Church, now located on Garza Street and renamed Our Lady of Guadalupe. Brooks County also includes the Church of Saint Anne at Encino and other Catholic facilities and organizations. The school of the Ursuline Sisters prospered for 38 years before closing in 1965. Among the church's mainstays were Lino Trevino (1857-1935), Charles Premont (1867-1941), J.J. Allan (1871-1943), Mrs. J.T. Maupin (1875-1967), and Mrs. R.E. McBryde (1879-1966).
