On September 18, 1650, Charles II of England, granted the original tract of the Northern Neck of Virginia, to seven followers including Lord Culpepper.

On September 7, 1688, after acquiring the interests of the remaining grantees, Lord Culpepper was recognized as the sole owner of the Northern Neck.

On September 22, 1730, acting as Fairfax's agent, he executed a deed to ten of his sons and grandsons: 50,212 acres of land in what are now Clarke, Warren, and Frederick Counties, Virginia.

[5] In 1798, after the legal problems had been sorted out, Robert Carter Burwell inherited his grandfather's land of about 1,000 acres lying roughly between Long Branch Creek and Rattlesnake Spring.

In the beginning of the 19th century Burwell began to plan his own home, just south of Rosney near Long Branch Creek.

When Hugh M. Nelson and his wife Adelaide moved to Long Branch with their three-year-old daughter, Nannie, they started a large renovation and expansion of the property.

Hugh Nelson took command of the Clarke Cavalry,[14] served as a justice of the peace,[15] and was a vestryman at Christ Church.

In 1861, Hugh M. Nelson organized the Clarke Cavalry and reported for duty to fight with the Confederate Army.

[23] At the time of the sale, Long Branch had deteriorated and the Hewitt's worked to repair and renovate the house.

Built in 1811, Long Branch is a Federal style, two-story, Flemish bond, brick mansion.

The south façade was the original front of the house; changing after Harry Isaacs constructed new roads throughout the property.

He added the west wing to balance the exterior of the house and completed a number of extensive reconstructions.

"In the summer you will be plagued in the evening after dinner by the western sun, and in the winter by the N. West wind."

The back staircase to the left of the central stair is believed to be a direct result of Latrobe's comments.

The Valley farmers took advantage of the fertile land and created a booming commercial agricultural industry.

The wheat from Long Branch was likely ground at the nearby Burwell-Morgan Mill in Millwood and transported to the markets in Alexandria before being shipped to Europe.

Letters written by the residents of Long Branch explain their hope for the corn after the wheat crop failed.

Over the years, Long Branch has raised a variety of livestock, including cow, sheep, horses, pigs, and chickens.

Pictorial records and oral histories indicate that Long Branch had a grouping of outbuildings fairly close to the house.

The summer kitchen collapsed in 1965 and an office was rebuilt in its place and was paneled with wood from an old sheep shed.

The large horse barn, a machinery shed, two garages, and two houses near the north and south entrances of the property.

Abram Hewitt and Harry Isaacs continued the horse breeding tradition at Long Branch, each having their own well-known operations.

As a large wheat plantation, Long Branch used enslaved workers to tend to the fields as well as the families house and gardens.

In addition to the main farming tasks, slaves also tended to the flower and kitchen gardens and helped with the maintenance and cleaning of the mansion.

Tyson Gilpin, chaired the board of directors, oversaw the daily operation of the estate and Colette Poisson, as assistant to Isaacs, became the curator.

Long Branch Historic House and Farm hosts many special events and weddings on location.
