Located in Harris County, the city of Tomball is a part of the Houston metropolitan area. First settlers began to arrive in the early 19th century. Local land turned to be fertile and highly suitable for farming. Being a small community, the city got its name only at the beginning of the 20th century. Originally named Peck, a few years later, it was renamed in honor of Thomas Ball, the lawyer famous for his role in the local railroad construction. Rapid economic growth started in the 1930s when the Humble Oil Company (now known as Exxon) began its work on the fields around the city. In the next few decades, Tomball became a prosperous community with diverse opportunities for its residents and visitors.
