The citizens of the northern portion were strongly opposed to division, but the township was divided against their wishes on September 12, 1851.

It was named for Judge James Pollock, president of the district court that ordered the township to be divided, and a controversial figure at the time.

Since the citizens of Upper Fairfield Township opposed division, they were disturbed by its name.

Pennsylvania Route 87 crosses the west side of the township, following Loyalsock Creek.

Pennsylvania Route 864 has its western terminus at PA-87 in Farragut and leads east up the valley of Mill Creek, passing through Fairfield Center near the eastern border of the township and continuing east 8 miles (13 km) to Picture Rocks.

Williamsport, the Lycoming county seat, is 10 miles (16 km) southwest of the township.
