## History

European settlers began arriving along Breakneck Creek, a tributary of the Connoquenessing, circa 1800. Around the same time, present-day Zelienople and Harmony were settled. Among the first settlers in the area were James Magee (born in County Down, present-day Northern Ireland, in 1769) in the Connoquenessing Valley in 1797 and William Martin (born in Ireland) along Breakneck Creek. The Harmony Society also made its first settlement in the United States in present-day Jackson Township.
Jackson Township was ultimately formed from parts of Cranberry Township and Connoquenessing Township in 1854. Early industries in the area included coal, iron ore, and limestone extraction, timber production, and farming on the low-lying, flatter areas of the Connoquenessing Valley, where the fertility of the soil was conducive to it.
