Czech Protestant immigrants began settling in the Granger area in the early 1880s, many establishing family farms in the rich surrounding farmland. Their first organized worship service was held in a schoolhouse east of town, and services were conducted sporadically whenever a traveling minister was available. The Rev. Adolph Chlumsky, a Czech Brethren minister from Brenham, encouraged the local people to organize a church, and on July 10, 1892, they officially founded a congregation and elected him pastor. He commuted from Brenham to serve for the next 18 years. The congregation built its first church structure in 1901, and on December 29, 1903, under Chlumsky's leadership, the Evangelical Unity of the Czech-Moravian Brethren in North America, also called the Unity of the Brethren, was officially organized there. In 1910 Chlumsky was succeeded by the Rev. Josef Barton, Sr., who became the first resident pastor. The church continued to thrive over the years, serving the community with a variety of programs, and it remains an important part of Williamson County history.
