History
Thomas Ferguson, who, in 1791, bought 321 acre of land for 300 pounds in gold and silver coins, is credited with founding Pine Grove Mills. In 1800, he dammed Slab Cabin Run and built the first of the mills that would eventually give the town its name. According to local tradition, a grove of pine trees separating the sawmill from the gristmill along the run provided the rest of the name.

John Patton Jr., son of Centre Furnace ironmaster Col. John Patton, laid out the town of Pattonville at the east end of Pine Grove Mills in 1815, and the entire village went by Pattonville for a time.

The post office, founded in 1809, was continually known as the Pine Grove Mills post office, however, and the town eventually reverted to the original name.

The village celebrated its bicentennial in 2001. This included the publication of a book.

In June 2018, a farmers market began in the parking lot of St Paul Lutheran Church.

Beginning in 2018, the Centre Region Planning Agency, a department of the Centre Region Council of Governments, led the development of a small area plan alongside residents and Ferguson Township staff. On November 4, 2019, the Ferguson Township Board of Supervisors approved and adopted the plan. Early in 2020, the Board of Supervisors voted to create a standing committee to provide advice and recommendations on the implementation of the plan.
