The House that Grew: Discovering Warren’s Kirch-Ford-Terrill House

Two hundred years after its incorporation, Warren Township, New Jersey, manages to retain much of its rural charm. Nestled in the valley between the first and second ridges of the Watchung Mountains, this area avoided direct combat during the American Revolution, yet it played a crucial strategic role. General George Washington utilized the first ridge to survey British movements from New Brunswick to Staten Island.

Just miles from that ridge sits an architectural gem that appears on military maps from the Revolutionary War: the Kirch-Ford-Terrill House. Located at the corner of Mt. Bethel and Reinman Roads, this structure offers a masterclass in the agrarian development of the region.

The Mystery of Captain Ford

The house appears on a 1766 map, but its significance was solidified by Robert Erskine, Geographer of the Continental Army. His 1776 route maps identify a “Captain William Ford” living at the property.

Historians have struggled to identify which William Ford this was—records show 45 men by that name served in the war, four from New Jersey alone. While we cannot definitively connect a specific soldier to the deed, we know the house stood witness to the birth of the nation.

Anatomy of a Colonial Home

The construction of the house tells a clearer story than the deed records. The home was not built all at once; it grew organically along with the needs of its owners.

Phase 1: The Pioneer Core (c. 1750–1760) The original section was a simple “keeping room” with a sleeping loft above. Life centered around a massive ten-foot-wide open hearth with a reconstructed beehive oven.

Unique to this home is a brick “ash chute” designed to guide hot ashes from the oven directly onto the hearth floor—a clever convenience for the time.

Phase 2: The Saltbox Transformation (c. 1760–1770) To accommodate a growing family, a “lean-to” addition was built on the rear. This created the classic “Saltbox” shape, characterized by a long, sloping rear roofline similar to the Wick House in Morristown.

This addition served two vital functions:

1. The Cold Cellar: A room on the north side was sunken 17 inches below floor level. This drop in elevation kept the room significantly cooler, acting as a refrigerator for perishable goods.
2. The Borning Room: Located adjacent to the warm hearth, this small room was reserved for the sick, the elderly, and women giving birth, keeping them close to the heat source.

The Myth of the “Secret Room” Above the lean-to lies a hidden loft, accessible only by lifting a loose floorboard. Local lore suggests this was a hiding spot for Revolutionary soldiers or a stop on the Underground Railroad. However, historical evidence debunks this; the area was largely pro-slavery, making it an unlikely route for freedom seekers. It was likely just storage.

Phase 3: The Expansion (c. 1780) A large two-story wing was added to the structure, likely moved from another location and attached. This wing features higher ceilings and a brick front facade—a rare status symbol in this area indicating the owner’s wealth.

The Families Who Called it Home

Thomas Terrill (The Civic Leader): In 1796, Thomas Terrill moved in. He was Warren Township’s first clerk and wealthiest resident. A devout man, he paid $28 annually—a small fortune—for the best pew in the Mt. Bethel Baptist Church.

The Kirch Family (The Builders): In 1857, German immigrant builder John Kirch purchased the home. His family would own it for over 120 years. Kirch added the final major touches, including a shed kitchen and pantry.

Preservation Victory

In 1978, the property was purchased by Bell Laboratories, threatening the home with demolition. Thanks to a passionate campaign by local citizens, Warren Township acquired the house in 1980.

Today, after extensive restoration to its clapboard exterior and shutters, the Kirch-Ford-Terrill House stands as a museum, preserving the architectural DNA of early New Jersey life.
