Northbrook Historic District
Also known as: Marshall's Mill; Marshall's Station; See Also:Derbydown Homest
Why it's listed
Northbrook is a small village on both banks of the West Branch of the Brandywine River, where most of its buildings date from the 18th and 19th centuries. The Marshall family settled here in the early 1700s, and the farmhouse Derbydown, begun about 1720 and enlarged in 1764, anchors the district. Dr. Moses Marshall built a stone house in the late 1700s, and the Samuel and Lewis Marshall houses are stone farm houses of 1801 and about 1840. The village is also associated with Indian Rock, a marker of the Penn land purchase line of 1706, and with Indian Hannah, Chester County's last Lenni-Lenape resident, who was supported by neighbours under an 1798 agreement. The Wilmington and Northern Railroad reached the village in the 1870s, bringing a station, a post office established in 1871, and a coal and lumber business. The village remains largely intact, with its saw mill still in use.
Significance in brief: The district is significant for its association with the Lenni-Lenape Indians, the Marshall family, a prominent Chester County family whose members farmed and milled here from the 18th century, and the Wilmington and Northern Railroad, which shaped the village's later development. Its riverside location was the common factor in these associations.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
