The first Skillmans were Dutch, but lived in England before moving to Brooklyn in 1664, according to family accounts.

In 1729, Thomas Skillman ventured westward, buying some 500 acres (2.0 km2) of farmland on the Millstone River, near the village of Rocky Hill, for his sons, Jan and Isaac.

Joseph A. Skillman, was a teamster who owned "wild Missouri mules," according to family accounts.

When railroad workers were trying to lay tracks, their horses got bogged down in thick, clay mud, and Joseph A. Skillman came to the rescue with his mules.

Railroad officials also socialized at the home of another Skillman nearby, and the new train station was named for the family.

Also in Skillman was the sprawling New Jersey State Village for Epileptics, a 250-acre (1.0 km2) complex opened around 1900 that had its own dairy, laundry, and movie theater.
