 On August 22, 1969, Pope Paul VI separated 28 counties of north central Texas from the Catholic Diocese of Dallas–Fort Worth to form the Diocese of Fort Worth (the remaining territory went back to the "Diocese of Dallas" designation).Two months later, on October 21, Bishop John J. Cassata, a native of Galveston, was installed in St. Patrick Cathedral as Fort Worth's first ordinary.From 1969, when the Diocese of Fort Worth was established, to 1986 the Catholic population increased from 67,000 to 120,000.
