Thornbury Township lies in the drainage area of the Delaware River, named in honor of Thomas West, 3rd Baron De La Warr, governor of the colony of Virginia. The river and its bay were explored by Henry Hudson in 1609, and over the next several decades the region was variously claimed by the Swedes, the Dutch, and the English. Its original human inhabitants were the Lenni-Lenape tribe of American Indians.
Once the Dutch were defeated, King Charles II of England made his grant to William Penn in order to found the colony which came to be named Pennsylvania. The land within the present boundaries of Thornbury Township was taken up by "first purchasers" from William Penn. The original grant documents were copper-plate prints on parchment; some still survive and show a price of 100 English pounds for 5,000 acres (2,000 ha).
The Court of Equity in Chester recognized a separate Thornbury Township in 1687, and appointed township officers. At the time, the area was in Chester County, one of the original counties chartered by William Penn; Delaware County had not yet been formed. Thornbury was named after the English birthplace of the wife of George Pearce, who in 1685 had been granted title to 490 acres (200 ha) in the township.
The Battle of Brandywine, the only major battle of the American Revolution fought in Pennsylvania, was within sight and sound of the western part of the township; follow-up military operations took place in the township (see below).
In 1769, the Pennsylvania Assembly authorized the division of Chester County and the creation of Delaware County. In plotting the boundary between the two, Thornbury Township was divided. Border landowners were asked if they wished to remain in Chester County or be in Delaware County. The line thus drawn was quite irregular, and as a result, the northern boundary of the Delaware County township (like the southern boundary of its Chester County counterpart) is distinctly jagged (see map).
Thornbury Township was enlarged by annexing the northern portion of Aston Township in 1837; that township was dissolved. The boundaries of Thornbury have remained unchanged since. The township is the location of "Thornbury" house, home of Revolutionary War figure Persifor Frazer. After the Battle of Brandywine, his wife Mary stood down a British raiding party in a celebrated incident. The house and barn survived the war, but are now in ruins.
In September 2000 the Delaware Nation of Oklahoma received 11.5 acres of land in Thornbury Township, Delaware County, Pennsylvania
