The Story
Dennis Mahoney, a Connecticut contractor, came to Texas in the late 1800s to build Trinity University in Waxahachie, laying its cornerstone in 1902. In 1904 he raised this stately house for himself, which later passed to the family of his son-in-law W. B. Thompson. The Ellis County Historical Museum and Art Gallery has since restored the home.
Why it matters
The house links the builder of an early Texas university to the domestic architecture of a prospering county seat, preserving a tangible piece of the men who literally constructed the region's institutions.
The story behind this marker
AI contextThe era
At the turn of the twentieth century, Waxahachie was a thriving county seat. Ellis County was one of the richest cotton-growing areas in Texas, and that money paid for grand public buildings and handsome homes. The town is still known for its ornate Victorian and turn-of-the-century architecture.
This was the early Progressive Era, a time of growth and civic ambition across America. Towns competed to attract colleges, railroads, and businesses, because those institutions brought money, prestige, and people. Winning a university was a real coup for a town like Waxahachie.
Trinity University's move to Waxahachie was one of those wins. The Presbyterian-affiliated school came to town and needed a campus, and building one called for skilled builders. That's where Dennis Mahoney comes in.
People & events
Dennis Mahoney was a contractor and builder from Connecticut. He came to Texas in the late 1800s to build Trinity University in Waxahachie. The cornerstone was laid on March 21, 1902, the kind of ceremony that meant a great deal to a town hoping a college would shape its future.
Mahoney then did what many builders drawn to a project have done: he stayed. He settled in Waxahachie, and in 1904 he built this stately house for himself. You can think of it as a builder's own showpiece, a home that displayed the skill he had brought south from New England.
The house later passed to the family of his son-in-law, W. B. Thompson, which is why it carries both names. Trinity University itself eventually left Waxahachie and is now in San Antonio. But the house its builder raised is still here. It was restored by the Ellis County Historical Museum and Art Gallery, Inc., and is preserved for future visitors.
Its place in the American story
This house tells the story of the skilled tradespeople who built America's institutions. We remember the founders and presidents of colleges, but builders like Mahoney actually raised the walls. Many traveled long distances for this work, carrying their craft from one region to another.
It also reflects how small American towns chased growth around 1900. Colleges, courthouses, and railroads were the prizes, and communities invested heavily to win them. Trinity University's time in Waxahachie is one chapter in that competition.
Finally, the house is an example of community-led historic preservation. Across the country, local historical societies and museums have saved buildings like this one, keeping them standing long after the people who built them were gone.
If you visit
Look closely at the house itself. It was built by a professional builder for his own family, so it's worth studying the craftsmanship and proportions. A builder putting up his own home had every reason to show what he could do.
Waxahachie is a wonderful town for walking and admiring architecture. Downtown is anchored by the famous Ellis County Courthouse, and the surrounding neighborhoods are full of historic homes. Give yourself time to wander.
Waxahachie is an easy drive south of Dallas, which makes it a good half-day trip or a stop on a longer drive through North Texas. Since the house has been restored by a local historical organization, check ahead to see whether it's open to visitors during your trip.

Dunlap - Simpson House
Waxahachie, TX
Built in 1890-91, this exuberant Queen Anne Revival house—complete with hexagonal and octagonal rooms—was the home of Judge Oscar E. Dunlap, a Waxahachie banker, industrialist, and civic leader. Dunlap founded the Sims Library and championed the Good Roads movement, and the home later passed through a succession of prominent local families. It stands as a showpiece of late-nineteenth-century architectural ambition.
City of Ferris
Ferris, TX
Ferris grew from an 1851 cluster of land-grant pioneers into a chartered town when the Andrews family deeded a 100-acre townsite to the Houston & Texas Central Railway in 1874, naming it for Judge J.W. Ferris. The railroad brought a post office, a cotton gin, and a newspaper, and by 1895 the community had found its lasting identity as a brick-making center. The short-lived Ferris Institute reflected the town's early reach for education.
Town of Lancaster
Lancaster, TX
Kentucky-born A. Bledsoe settled here in 1846 and, with the Rawlins family, laid out this town around 1852, naming it Lancaster after the Kentucky town his grandfather had founded. Stores, churches, a school, and mills soon clustered on the one-square-mile townsite, and during the Civil War a Confederate pistol factory operated here. The town weathered repeated fires and the rise and fall of Randolph College, living for a century as a cotton-market town whose fortunes rose and fell with the crop.
John C. Pelt
Duncanville, TX
John C. Pelt came of age in the cotton country south of Dallas, orphaned young and raised by relatives in the small farming town of Duncanville. A carpenter and builder by trade, he shaped the growing community with his own hands, raising homes and civic buildings—among them the structure that became Central Elementary School. In 1927 he built his own family home on this spot, and the local Masonic lodge later took his name in tribute.
