Haverford Township is a home rule municipality township in Delaware County, Pennsylvania, United States.[3] Haverford is named after the town of Haverfordwest in Wales. It is a commuting suburb located due west of Philadelphia and is officially known as the Township of Haverford. Despite being under a home rule charter since 1977, it continues to operate under a Board of Commissioners divided into wards,[3] as do "First Class" townships that are still under the Pennsylvania Township Code. Haverford Township was founded in 1682 and incorporated in 1911.

Haverford Township contains portions of the unincorporated communities of Haverford, Ardmore, and Wynnewood and the census designated places of Bryn Mawr and Drexel Hill. The unincorporated community of Havertown lies wholly within Haverford Township. Much of Haverford Township developed as part of the Philadelphia Main Line, growing alongside the Paoli/Thorndale Line, Norristown High Speed Line, and the former trolley routes, now SEPTA Route 103 and SEPTA Route 104.[4] The township population as of the 2020 census was 50,431, making it the 16th-most populous municipality in the state.
Haverford Township holds the distinction of having hosted two different men's major golf championships at two different golf clubs: Merion Golf Club hosted the 1934, 1950, 1971, 1981, and 2013 U.S. Open, and Llanerch Country Club hosted the 1958 PGA Championship.
Haverford, along with Upper Darby, Cheltenham, Lower Merion together form as the major inner ring suburbs of Philadelphia.
History
edit17th century
editHaverford Township was laid out by William Penn as part of the Welsh Tract or Barony. In 1681, a representative group of Welsh Quakers met with Penn to discuss their settlement having purchased forty thousand acres of land which today comprises all of Haverford, Radnor and Lower Merion Townships. "Companies of Adventurers" were formed, with the most prominent person in each taking out the patent on 5,000 acres of land as trustee. The first three families arrived in Haverford Township in 1682. Lewis David, Henry Lewis, and William Howell selected land along the southern border. The original settlers, led by John Roberts who had negotiated with William Penn in 1684 to constitute the Tract as a separate county whose local government would use the Welsh language never saw their dream realized. The earliest map of Penn's province dates from 1687.
The area was primarily agricultural until the second decade of the 20th century. The census returns of 1860 show the value of livestock as $62,485.00; animals slaughtered $11,255.00; 46,049 bushels of grain harvested and the value of orchard and garden produce, $4,090.00.
The two creeks that mark part of the township boundaries, Cobbs Creek and Darby Creek provided mill seats for the early settlers. "As early as the year 1688 a small grist-mill, known as the "Haverford Mill," was built on Cobb's Creek, near where that stream is crossed by the road leading past Haverford Meetinghouse.[6]
18th century
editDaniel Humphreys purchased the property in 1703 and built a sawmill and fulling and dyeing mill. These were added to Dennis Kelly's holding in 1826 and became the Castle Hill Mills. This site is just north of Eagle Road on the west bank of Cobb's Creek.
On Darby Creek to the west, Richard Hayes Jr., David Morris and Samuel Lewis erected a gristmill, known as Haverford New Mill, in 1707. Later a sawmill was attached. This mill operated until 1904. Near the border with Marple Township, Humphrey Ellis operated a very early fulling mill. In 1807 Henry Lawrence built a sawmill on this site, and in 1832 his son, William, built a gristmill close by. The sawmill remained in the family ownership for more than 125 years, and was, until its demolition, the oldest industry extant in Haverford Township.
About 1800 grist and sawmills were built on the headwaters of Cobb's Creek by Peter Brown, and in 1810 Jonathan Miller built grist and sawmills at what is now the Juncture of Mill Road and Karakung Drive.
19th century
editIsrael Whelen Sr., built the Nitre Hall Powder Mills on Cobb's Creek, which were in operation by 1810. During the American Revolution very little black powder was manufactured in this country, and it was needed for engineering and mining. Between 1810 and 1840, these mills were the second largest powder mills in the U.S., with production of 800,000 pounds in 1812. The mills ceased operations in 1840 and were sold to Dennis Kelly, who converted them for the manufacture of cotton and wooden goods.[7]
In 1814, Dennis Kelly borrowed capital to purchase a mill-seat on Cobb's Creek. He erected a small wooden factory known as Clinton Mills. This was a highly successful venture and, after enlarging the mill, he built Cedar Grove Mill further downstream. Dennis Kelly provided material for the U.S. government from 1817 until 1860 with contracts ranging from $1,800.00 to $41,370.00. Improved transportation opened the township to development.
20th century
editThe transformation of Haverford Township from an agrarian spread of farms and mills began just after the turn of the 20th century. The railroads bought acres of land west of Cobb's Creek for their planned developments. Rail lines ran from 69th Street in Upper Darby outward to Ardmore, West Chester and Norristown. Along the rail lines the railroad built the first planned suburban communities Llanerch, 1897 and the most fully developed, Brookline, 1909. While Beechwood, Oakmont and Manoa date from the same period the major housing tracts do not appear until after World War II along with the development of Chatham Park. These communities are now included under the postal address "Havertown."
Several golf courses were developed. Merion Cricket Club Golf Association incorporated Clifton Hall an old farmhouse, in their clubhouse. They have 140 acres in the main course or East Course and 160 acres in the West Course. The Llanerch Country Club consists of 126 acres. The Pennsylvania Railroad Golf Club was established in 1925 on 109 acres bounded by Earlington Road, Manoa Road and City Line. This property was sold in 1943 to Warner West Corporation, which developed Chatham Park.
Education
editThe first building erected for educational purposes was the Federal School, in 1797. During the 1800s four additional one-room schools and one parochial school were built. The latter part of the 19th century was the beginning of the present school system. After World War II, additions were made to existing schools, a new high school and three one-story elementary schools were built. Today there is one middle school, one senior high, five elementary schools, four parochial schools and four private schools.
Historical sites
editLawrence Cabin
editDavid Lawrence was one of the early Welsh settlers in Haverford Township. He emigrated with his wife Elinor Ellis and her family in 1684, and took up part of his father-in-law's land grant. His son Henry Lawrence purchased 209 acres along Cobbs Creek in 1709. It has not been determined whether the log house predates this purchase, but a 2 1⁄2-story stone addition was built c. 1730, and later a clapboard summer kitchen was added. It became known as the Three Generation House, and remained in Lawrence family ownership until 1942.[8]
Federal School
editThe first record of the purchase of land for a school in Haverford Township was October 29, 1797. Alexander Symington received 5 shillings for an irregularly shaped building lot of one quarter of an acre and three perches near the present day intersection of Darby and Coopertown Roads. Payment for the land was made by five trustees: Philip Sheaff, William Brook, Francis Lee, David Lyons and Benjamin Hayes Smith, "for the purpose of erecting a school thereon for the use of said Township of Haverford". The 1797 Federal School is on the National Register of Historic Places.[9]
Pont Reading House
edit"Pont Reading House" is situated on the Easterly side of Haverford Road, Haverford Township, Delaware County, Pennsylvania, at the corner where the Ardmore Trolley passes en route between Brookline—Oakmont and Ardmore, and near Ardmore Junction Station of the Philadelphia and Western Railway. It was the home of Joshua Humphreys, the shipbuilder and naval architect known for constructing the original six frigates of the United States Navy. Here, this beautiful specimen of early American homes still stands, in an excellent state of preservation and repair, as it has since 1813, when the front section was built and added to the middle three-story section erected 1730–60, which in turn was then added to the rear and original two-story structure, built possibly as early as 1683. One of the log walls of this first and original section can still be seen as one enters a door on one of the sides thereof, All surrounded and shaded with some large trees, of the original forest, still surviving.[10]
Nitre Hall
editThe Nitre Hall Powder Mills, which gave the valley its name, were built by Israel Whelen shortly after 1800. The young nation had growing needs for explosives, and the mills prospered with an output of 800,000 pounds during the War of 1812. Nitre Hall Mills produced a quality and quantity of black powder in the U.S. second only to the Dupont Mills on the Brandywine. After the powder mills closed in 1840, Dennis Kelly bought the property and converted the buildings to the manufacture of textiles.[11] Nitre Hall is on the National Register of Historic Places.[12]
Grange Estate
editThe Grange Estate, also known as Maen-Coch and Clifton Hall, is a historic mansion in Havertown, Pennsylvania, near Philadelphia, in Delaware County, Pennsylvania. Built in 1750 and expanded several times through the 1850s, it was purchased by Haverford Township in 1974. The building was added to the National Register of Historic Places in 1976 as The Grange.
