McAllister's Mill Underground Railroad Station

Cumberland Township, Adams County, Pennsylvania

Marker Inscription

At their grist mill on nearby Rock Creek, James McAllister and his family provided temporary shelter to hundreds of fugitive slaves. Now in ruin, it was part of one of the earliest UGRR networks through which freedom seekers passed on their way north. It was the site of a significant gathering of abolitionists on July 4, 1836, that led to the formation of the Adams County Anti-Slavery Society, an early and influential abolitionist organization.

The Story

On the eve of the Civil War era, the McAllister family's grist mill on Rock Creek in Adams County became a haven for people escaping slavery. James McAllister and his family sheltered hundreds of freedom seekers as part of one of the earliest Underground Railroad networks carrying them north. On July 4, 1836, the site hosted a gathering of abolitionists that gave birth to the influential Adams County Anti-Slavery Society.

Why it matters

This quiet Pennsylvania mill was a working link in the secret network that helped hundreds toward freedom and an early cradle of the organized abolitionist movement.

Lincoln Cemetery

Gettysburg, PA · est. 2003

Founded in 1867 by the Sons of Good Will, Lincoln Cemetery gave Gettysburg's African American citizens and soldiers a dignified resting place they were otherwise denied. Roughly thirty veterans of the United States Colored Troops lie here — men who fought for the Union but were barred by segregation from burial in the town's famous National Cemetery. Later generations of Black veterans from the Spanish-American War through Korea joined them in ground first known as Good Will Cemetery and renamed for Lincoln in 1920.

Thaddeus Stevens

Gettysburg, PA · est. 1954

Before he became one of the most powerful and uncompromising figures in Congress, Thaddeus Stevens lived in Gettysburg, leaving in 1842. Here he built his early career as a lawyer and ironmaster while championing two causes that defined him: the abolition of slavery and the defense of free public schools in Pennsylvania, which he famously fought to preserve in 1835. From these Adams County beginnings he rose to lead the Radical Republicans and shape Reconstruction after the Civil War.

Daniel Kaufman

South Middleton Township, PA · est. 2002

For more than a decade beginning in 1835, Daniel Kaufman risked ruin to help enslaved people fleeing north through Cumberland County. His barn and the dense woods nearby sheltered fugitives to whom he gave food and transport. In 1852 a Maryland slaveholder won a widely watched lawsuit against him, and Kaufman was fined the enormous sum of $4,000 for his defiance of the Fugitive Slave Law. He also founded the village of Boiling Springs.

Daniel Alexander Payne

Gettysburg, PA · est. 1991

Born free in Charleston at a time when education for Black Americans was often outlawed, Daniel Alexander Payne became one of the 19th century's most influential Black religious leaders. While studying at Gettysburg's Lutheran Seminary in 1837 he also taught here at the college, and he went on to be elected a bishop of the African Methodist Episcopal Church in 1852 and to lead Wilberforce University, one of the first colleges owned and run by African Americans.
