The story

How Mount Jackson came to be

From Wikipedia’s history of Mount Jackson.

Read it all →

North Beaver Township was formed in 1810, and Mount Jackson was founded within its boundaries five years later, eventually becoming recognized as the township's hub. Named for Andrew Jackson soon after his victory in the Battle of New Orleans, Mount Jackson was founded by John Nesbit on a plot of farmland that he owned. The farming village's earliest residents were mostly Scotch-Irish and Presbyterian, with many arriving from Cumberland County, Pennsylvania. The first person to build a house there was William Henry, who also became the village postmaster. The only stagecoach route from New Castle to the train station at Enon Valley ran through Mount Jackson until the Civil War, after which New Castle received its own train station.
