Circuit rider DeVilbiss came to the Republic of Texas in 1842 to minister on Hispanic borders in the southwest. He pioneered among immigrants and native Texians to promote harmony in varied cultures in this far outpost. In the county clerk's office in April 1844 he delivered the first sermon in English ever given in San Antonio, helping lay foundations for a confluence of civilizations. He inspired the organization of Oak Island Church in 1867 or 1868, and this 1872 building holds furniture made by DeVilbiss and his son.
