In 1796 the first recorded childbirth in Williamsport was James Russell the son of Mr. and Mrs. William Russell and grandson of James Russell of the Russell Inn and the first school was built as a one-room log addition to the building that would eventually become the first Lycoming County Courthouse.

The Underground Railroad, used by enslaved African-Americans to obtain their freedom in the 30 years before the Civil War (1860–1865) included routes from states in the South, which supported slavery, to "free" states in the North and Canada.
From 1830 until 1865, the underground railroad, a system of safe houses and routes for slaves escaping to freedom, operated in Lycoming County; many local abolitionists, including Daniel Hughes, served as conductors and agents.

Based on the oral history of Mamie Sweeting Diggs (1933–2011), fourth generation descent and great-granddaughter, Hughes, was a river raftsman on the Susquehanna river who had migrated from Oswego, New York.
He lived on the Muncy Indian Reservation until he acquired land off Freedom Road.
 During his trips transporting logs to Maryland, he brought escaped slaves back on foot from Baltimore, over Bald Eagle Mountain and hid them at his home and in the caves on Freedom Road.

Mamie's grandfather, Robert, helped his father, Daniel Hughes, hide escaped slaves in the caves behind their home on Freedom Road.
They fed them, nursed the sick back to health and delivered them safely to the next "station", The Apker House in Trout Run.
The Apker House was the home of Robert Fairies, abolitionist and president of the Williamsport-Elmira Railroad.
The railroad ran through his property where escaped slaves were hidden in the barn and house and then loaded into railway baggage cars for the trip to Elmira, NY, the next "station."

Mamie's grandfather, Robert passed the stories to his children, including Mamie's mother, Marion.
 Marion tended the family homestead, maintained Freedom Road Cemetery (where nine black Civil War vets are buried) and passed Daniel's stories down to her children.

In 1849 the Market Street Bridge was built over the West Branch Susquehanna River.
It was opened as a toll bridge to cover the state's costs of $23,797.
