The Story
Edward Shippen was one of colonial Lancaster's leading citizens, a lawyer and judge who chaired the local Committee of Observation as the Revolution approached. His home stood here for three decades in the mid-1700s, an era when Lancaster was among the largest inland towns in the colonies. He is remembered too as grandfather of Peggy Shippen, who married Benedict Arnold and became entangled in the most infamous treason of the war.
Why it matters
The site links a prominent Pennsylvania family to both the civic leadership of the Revolution and its darkest betrayal, showing how personal ties threaded through the era's public drama.
The story behind this marker
AI contextThe era
In the middle of the eighteenth century, colonial Lancaster was no frontier hamlet. It was among the largest inland towns in British America, a prosperous center of trade and craft where German and Scots-Irish families rubbed shoulders and the business of law, land, and commerce filled the streets. A leading citizen's home here was a place of consequence.
Into this rising town came men who shaped its early civic life. Before Lancaster County even had its full complement of institutions, someone had to serve as its first chief officer, and figures of standing built the houses and held the offices that gave the community its form. The home commemorated at this site stood through three decades of that formative era, from mid-century into the Revolution itself.
Those decades carried the colonies from confident subjects of the Crown toward open rebellion. A house occupied continuously through that span would have watched the mood of its town change from loyalty to unease to resolve — the slow turning that this marker's own dates quietly bracket.
People & events
For thirty years this was the home of Edward Shippen — lawyer, judge, and a pillar of colonial Lancaster's civic order. As chairman of the local Committee of Observation, he stood at the point where ordinary community leadership met the machinery of revolution: such committees enforced the colonial boycotts and kept watch over local loyalties as the break with Britain approached.
An earlier occupant of the site was Thomas Cookson, remembered as the first burgess of Lancaster County — a founding figure of the town's official life. The thread from Cookson to Shippen is the thread of a community organizing itself, generation by generation, into a place with courts, offices, and leaders of its own.
And then there is the granddaughter. Shippen was grandfather to Peggy Shippen, who married Benedict Arnold — the American general whose name became a byword for treason after he plotted to hand West Point to the British. That family connection links this respectable Pennsylvania household to the most infamous betrayal of the entire war.
Its place in the American story
The Revolution was not only fought by soldiers; it was organized by committees, magistrates, and local men of standing who lent their credibility to a dangerous cause. Edward Shippen's role as a committee chairman shows how the rebellion took root in the everyday authority of the towns — how respectable judges and lawyers became instruments of a break with the Crown.
Yet the same site opens onto the war's darker human drama. Through his granddaughter's marriage to Benedict Arnold, this family's story runs straight into the question that haunted the Revolution: where does loyalty lie, and what turns a patriot into a traitor? The line between the two could pass through a single family.
That is why this quiet address carries such weight. It holds together the two faces of the era — the sober civic leadership that built the movement and the personal entanglements that nearly undid it — reminding us that great national events were lived out through particular people and their kin.
If you visit
There is no grand mansion to tour here; you're visiting a site, a spot on the map where a notable house once stood. Let that absence work on your imagination. Picture a substantial home occupied by the same family for three decades, its rooms busy with the law and the politics of a town on the edge of revolution.
As you stand here, hold two very different images side by side. One is of a respected judge chairing the committee that helped steer his community toward independence. The other is of his granddaughter, whose marriage would tie the family name to America's most famous act of treason. Few sites let you feel both the honor and the heartbreak of the era at once.
Set this stop within a wider walk through old Lancaster. The town was a place of real importance in colonial America, and markers like this one turn its streets into a map of the people who made — and tested — the young nation.

The stone church dedicated in 1766 still guards the graves of two Pennsylvania statesmen of the Revolutionary era, Thomas Wharton and Governor Thomas Mifflin.
