Long before it had a name, Swisshelm Park was home to the Susquehannock and Iroquois Indians. Like the adjacent borough of
Swissvale, Pennsylvania, Swisshelm Park is named after the Swisshelm family, which moved to the area in 1800, although the land was also known to locals as Deniston Park or North Homestead. John Swisshelm (1752–1838), a veteran of Valley Forge, purchased a grist mill from William Pollock in 1808 and built a small log cabin in Nine Mile Run Hollow. The approximate location of the Swisshelm family homestead was just west of what is now S. Braddock Avenue and W. Swissvale Avenue, with the grist mill likely buried where the adjacent parkway now sits. The largely Scotch-Irish settlers in the area took their grain to Swisshelm's grist mill for grinding, which then made its way to Pittsburgh via the old Braddock Road. - and an organizer of the

It was Jane Swisshelm who gave the Borough of Swissvale its name and for whom Swisshelm Park was named. Before the coal industry moved into Swisshelm Park, the area was mostly farmland. One prominent land-owner in the area was William S. Haven, who was a close friend of
Andrew Carnegie's and one of wealthiest men in Pittsburgh at the time. gained notoriety during the Civil War for her generous support for the Union troops at nearby Camp Copeland (in the Braddock Borough). She is said to have made daily trips to the camp and, at her own expense, provided the troops with home cooked meals while attending to the sick and dying. Other homesteads in the area were owned by Robert Milligan, John McKelvy, Samuel Deniston, Thomas Dickson, Alexander Gordon, J. S. Newmyer, and Col. William G. Hawkins, all of whom now have schools and streets named after them in Swissvale,
Edgewood, and surrounding areas. The building of the Pennsylvania Railroad through the area in 1852 encouraged industry. The Dickson-Stewart Coal Company began operations in 1866, attracting miners and their families. Swisshelm Park was incorporated into the City of Pittsburgh in 1868, relatively late in the city's history, when Jane Swisshelm was 53 years old. However, as late as the 1930s, residents noted that they were often not considered by others to be "city residents", given the rather isolated nature of the neighborhood. ==Jackson family and Windermere Drive==
