Fergus M. Bordewich

GROWING UP in northwest Yonkers, Fergus M. Bordewich, an author and journalist, was intrigued by stories that fugitive slaves had founded the nearby neighborhood of Runyon Heights, where many residents were African-American. ”My mother, LaVerne Madigan, was a national figure involved in civil rights, and she often cited the supposed fugitives as models who defied injustice in pursuit of freedom,” he said.

But while researching his fourth book, Bound for Canaan: The Underground Railroad and the War for the Soul of America, Mr. Bordewich, 57, learned that the Runyon Heights story was a myth, ”one of the classic Underground Railroad legends,” he said.

Still, the plight of fugitive slaves had formed ”the warp and woof of my own childhood,” said the author, who lives in Barrytown in Dutchess County. After visiting a community founded by former slaves in Canada in 1998, Mr. Bordewich said, he became determined to find out ”who these people were and what they had endured.”

What he learned while writing Bound for Canaan,published in April by HarperCollins, was that the Underground Railroad was far more than a picturesque story.

”It was the first interracial political movement in American history,” he said. ”It was the first mass movement of civil disobedience after the American Revolution. It was the first political movement born from evangelical religion—evangelical Protestantism—and also the seedbed of the American women’s movement.”

And although the tales about Runyon Heights turned out not to be true, he said, Westchester and its environs are dotted with historical sites along the Underground Railroad. These include the John Jay Homestead in Katonah; a Quaker meeting house in Purchase; the Oblong Meeting House near Pawling; and the Nine Partners Meeting House outside Millbrook.
