About
Thornbury Township, Delaware County was incorporated in 1687 — one of the earliest townships chartered by William Penn — and named after Thornbury, Gloucestershire, England, the birthplace of Ann Gainer Pearce, wife of the township’s first land grantee. The Thornton Village Historic District, located at the intersection of Glen Mills Road and Thornton Road within the township, was listed on the National Register of Historic Places in 2006 and includes 13 contributing structures built between 1750 and 1855, including the Yellow House — a Revolutionary War-era inn that later housed one of the nation’s oldest continuously operating post offices, established in 1829. Residential development expanded substantially after World War II and again in the 1990s and 2000s, producing a housing stock that ranges from mid-century detached homes on older farm roads to builder-constructed colonial subdivisions on platted lots, all served by the West Chester Area School District with Sarah W. Starkweather Elementary as the most common assignment for the 19373 ZIP.
Specifications
Home Stock
The housing stock is genuinely mixed: older roads carry stone colonial and cape cod homes built from the 1930s through 1950s, while post-1990 builder subdivisions — including Thornbury Hunt (Toll Brothers, circa 1993) and Tall Trees at Thornbury (Toll Brothers, circa 2005) — feature four-bedroom colonials with attached garages on one-third to two-fifths acre lots. All public records-recorded transactions in the 180-day window were detached single-family homes.
Location & Access
Pennsylvania Route 926 borders the township to the northwest; Route 352 cuts through the northeast section. U.S. Route 1 (Baltimore Pike) runs along the southern edge. Glen Mills Road and Thornton Road intersect at the historic village center. Cheyney Road provides access to Route 1 and the Blue Route (I-476).

Worth Asking
Have you considered that the 19373 ZIP code captures both the historic village of Thornton and the George W. Hill Correctional Facility on Cheyney Road — and that ‘Thornbury’ as a community label in public records reflects the full township, not a single gated or platted subdivision — meaning two homes with identical ZIP codes and school assignments could sit in dramatically different micro-locations?
Common Questions
What schools serve the Thornbury Township / Thornton 19373 area?
The West Chester Area School District serves the township. Sarah W. Starkweather Elementary is the most common assignment for the 19373 ZIP code. Students then feed to Stetson Middle School and Bayard Rustin High School. Starkweather ranks in the top 30% of Pennsylvania elementary schools by combined math and reading proficiency. School zone boundaries can change; buyers should verify their specific parcel’s assignment directly with the West Chester Area School District before closing.
Is there a homeowners association for Thornbury / Thornton 19373?
There is no township-wide HOA. Individual named subdivisions within the ZIP code maintain their own associations — Thornbury Hunt, for example, has an active HOA headquartered at PO Box 217, Thornton PA 19373. Older homes on established roads throughout the township typically carry no HOA obligations. Buyers should confirm HOA status for any specific property in public records disclosures, as the ‘None found’ public records flag reflects the township average, not every parcel.
What outdoor recreation is accessible from Thornbury Township / Thornton 19373?
Ridley Creek State Park — a 2,606-acre Delaware County park approximately 16 miles from downtown Philadelphia — offers more than 12 miles of hiking trails, a 5-mile paved multi-use trail open to jogging and bicycling, fly fishing on Ridley Creek, and the Colonial Pennsylvania Farmstead living history site. The park is adjacent to John J. Tyler Arboretum. Within the township, the Thornbury Township Historical Commission maintains interpretive panels at Thornbury Park and the Frazer Ruins, documenting the site of Revolutionary War-era Persifor Frazer’s property.
Items to Verify with Your Agent
A few specifics on this page are sourced from secondary aggregators or older filings. Confirm before relying:
- Entity Type — The preset entity_type of ‘subdivision’ is likely incorrect. Public records label ‘Thornbury’ with ZIP 19373 and mailing city Thornton appears to capture Thornbury Township, Delaware County as a whole — a municipal township with mixed housing stock — not a discrete named subdivision. Overridden to ‘borough_or_community’. Cyr Team reviewer should confirm which specific public records boundary or community name is being tracked.
- Avg Year Built (1946) — An average year built of 1946 is plausible for a township-wide capture that blends pre-war stone farmhouses, post-war cape cods, and 1990s-2000s builder colonials. However, this figure cannot be verified as specific to a named subdivision. If the public records entity is township-wide, the 1946 average is directionally correct but not tied to any single development era. Flagged for review.
- Approx Homes — Wikipedia cites 1,387 housing units (2000 Census) for Thornbury Township, Delaware County, but this is a township-wide figure nearly 25 years old and cannot be attributed to a single subdivision. Left null.
- Hoa Name — No township-wide HOA exists. Individual subdivisions (e.g., Thornbury Hunt HOA) have their own associations. Public records ‘None found’ is consistent with township-level capture. Left null to avoid falsely applying a subdivision HOA to all properties.
- Builder — No single builder is responsible for township-wide development. Named builders (Toll Brothers for Thornbury Hunt and Tall Trees; David Cutler Group for Estates at Mill Creek) apply only to their specific subdivisions. Left null at township level.
- Interior Sqft Range Text — Square footage range is synthesized from named subdivisions within 19373 (Thornbury Hunt: 2,600–3,800 sq ft; Estates at Mill Creek: ~4,000 sq ft median; Tall Trees: ~4,100 sq ft median) plus older stock. No verified range for the full township’s older mid-century homes.
- Cross Border Note — School Boundary Risk — Both Thornbury Township (Delaware County) and Thornbury Township (Chester County) feed the same West Chester Area School District schools including Sarah Starkweather. School boundary assignments should be verified at the parcel level with the district before purchase.
