Original dwelling built by Ebenezer styles about 1752. Lighthorsemen quarter here during revolution. House in large the 1868 by Jonathan Roberts, founder of library association 1881.
The Story
Glenbrook began as a modest colonial dwelling, raised around 1752 in the New Jersey hills near Morris Plains. During the Revolution, mounted 'light horse' troops were quartered here, tying the house to the war that swept through the region. Enlarged in 1868 by Jonathan Roberts — who went on to found a local library association in 1881 — it grew from a working farmstead into a fixture of community life.
Why it matters
The house traces more than a century of New Jersey history under one roofline, from colonial settlement and Revolutionary War service to the civic-minded improvements of a later age.
The story behind this marker
AI contextThe era
In the middle of the eighteenth century, the hills around present-day Morris Plains were still frontier farmland — a landscape of woodlots, stone-cleared fields, and scattered dwellings a day's ride from the busier towns of colonial New Jersey. When the first rooms of this house went up around 1752, the colony was still firmly under the British crown, and a family here would have measured wealth in acreage, livestock, and the labor it took to wring a living from the soil.
Morris County sat in a strategically important corner of the colonies. Its iron forges, its farms, and its position in the rolling country west of New York City would soon matter enormously. What began as a quiet agricultural district would, within a generation, find itself close to the center of a war for independence.
A modest dwelling raised in this era was rarely built all at once. It grew as a family grew — a room added here, a wing there, across decades. This house carries that layered history in its very walls, which is part of what makes an old homestead like it such a satisfying thing to stand before.
People & events
The house is tied first to Ebenezer Styles, remembered here as the builder of the original dwelling around 1752. His name anchors the site to its colonial beginnings, to the ordinary work of settlement and farming that filled the years before the Revolution reached New Jersey.
Then came the war. The marker records that mounted 'light horse' troops were quartered at the house during the Revolution. Light horse meant cavalry — fast-moving mounted soldiers used for scouting, carrying messages, and screening the movements of armies. That such troops were billeted here is a reminder that the Revolution was not fought only on distant battlefields; it moved through farmyards and private homes, which fed, housed, and sheltered the men who kept the war going.
More than a century of the house's life then gathers around Jonathan Roberts, who greatly enlarged the dwelling in 1868 and went on to found a local library association in 1881. In him you can see a familiar nineteenth-century figure: the prosperous local citizen who turns private means toward public good. A library association was a civic act — a bet that a community grows stronger when knowledge is shared — and it carried the old farmstead into a new and more public chapter.
Its place in the American story
Houses like this one are where the big American story touches the ground. The grand narrative of the Revolution is usually told through generals and famous battles, but armies could not move or survive without the countless ordinary homes that quartered soldiers and supplied them. A cavalry troop sheltering under a farmer's roof is the war at human scale — and it is the scale at which most people actually lived it.
The house also traces the long arc of American community life. From a colonial dwelling, to a site of Revolutionary service, to the home of a man who built up a library for his neighbors, it follows the country's own maturation — from settlement, to independence, to the civic-minded improvements of the later nineteenth century, when Americans poured energy into schools, libraries, and institutions meant to outlast any one family.
That a single roofline can hold all of that — more than a hundred years of change under one continuous story — is exactly why old houses are worth preserving. They are the connective tissue between the eras we usually study separately.
If you visit
Come to see a house that wears its history in layers. Knowing that the oldest part dates to around 1752 while a major enlargement came in 1868, let your eye look for where an older, plainer dwelling gives way to later, more ambitious additions — old homes rarely hide the seams of their own growth.
Stand for a moment with the Revolution in mind. It takes a little imagination to picture mounted troopers and their horses quartered on this ground, but that image is the marker's gift: it turns a quiet residential spot into a place where the war for independence actually passed through.
This is a small, local stop rather than a grand museum, and that is its charm. Fold it into a wider day exploring the Morris County countryside, whose farms and towns saw so much of the Revolution. Please remember that a historic home may be a private residence — admire it from the roadside, respect the property, and let the marker do the storytelling.

Cutler Homestead (1799)
Morristown, NJ
This homestead dates to 1799 and the farm of Silas Condict, a New Jersey patriot active in the cause of American independence. It later became home to the Cutler family, including Augustus W. Cutler, a congressman remembered as a champion of free public schooling in New Jersey. The site witnessed more than a century of the state's political and civic life.
Thomas Paine 1737-1809
Morristown, NJ
Thomas Paine was the pamphleteer whose words helped turn a colonial rebellion into a revolution. His American Crisis series, begun in the dark winter of 1776, opened with the immortal line about times that try men's souls and was read aloud to Washington's cold, discouraged troops across New Jersey's Revolutionary landscape. An Englishman by birth who later became a French citizen and an adopted American, Paine went on to write Rights of Man and The Age of Reason, works that carried the era's arguments about liberty and reason far beyond the new nation's borders.
Continental Army Encampment
Morristown, NJ
Through the winter of 1779–1780, the Continental Army made its main encampment around Morristown, New Jersey — a season of brutal cold and short supplies remembered as even harsher than Valley Forge. Among the officers wintering here was Brigadier General Henry Knox, George Washington's trusted chief of artillery. This marker recalls that grim, pivotal season when the army held together against long odds.
Arnold Tavern
Morristown, NJ
During the bleak winter after his daring victories at Trenton and Princeton, George Washington made Morristown a refuge for the Continental Army, and Colonel Jacob Arnold's tavern served as his headquarters from January to May of 1777. While the general planned from the tavern on the town green, his troops encamped in the nearby Lowantica Valley, rebuilding an army worn thin by the campaign. Morristown's hills and distance from British-held New York made it a natural stronghold in the middle years of the war.
