The Isaac Conroe Property
Conroe, Montgomery County, Texas
Marker Inscription
Temporary Montgomery County Courthouse. A native of New Jersey, Isaac Conroe (1834-1897) served with the Union army during the Civil War. Moving to Southeast Texas with his wife Margaret (Richardson) (1846-1896) in 1866, he lived at Lynchburg and Houston. In 1878 he built a sawmill at Haltom (12 mi. S) and three years later moved his business to the Beach community (2.5 mi. E). A tram line connected the mill with the main line of the International and Great Northern Railroad. The town of Conroe grew up around the intersection and Isaac conroe became the first postmaster of the new settlement. The original section of this residence was built by Conroe shortly after he purchased the site in 1885. Four years later he contracted with the county commissioners to use the property as a temporary courthouse.County records and offices were moved from Montgomery (17 mi. W) and remained here until a new courthouse was completed in 1891. In 1896 Conroe sold the house to his son William Munger Conroe (1870-1947), a prominent lumberman and oil man. Major additions were later made to the home, which was originally a two-story frame structure with an outside stairway.

The Story
A New Jersey native and Union Army veteran of the Civil War, Isaac Conroe moved to Southeast Texas in 1866 and in 1878 built a sawmill whose lumber business gave rise to the town of Conroe, connected by a tram line to the International and Great Northern Railroad. He became the settlement's first postmaster and built this residence in 1885. From 1889 to 1891 it served as the temporary Montgomery County courthouse until a permanent one was completed, and his son William later expanded the home.
Why it matters
Conroe's sawmill, railroad tram, and makeshift courthouse show how a single enterprising lumberman could conjure a whole East Texas town — and its government — out of the pineywoods.

Conroe
Conroe, TX
Conroe began in 1881 as Isaac Conroe's sawmill in the East Texas pine forest, at a spot where two railroads met and where the town was first known simply as Conroe's Switch. Lumbering brought early prosperity, and the settlement — still wild enough that a deer was once shot on the courthouse square — became county seat in 1889 and incorporated in 1904. The 1931 Strake oil discovery transformed the timber town into a booming petroleum center.
Willis
Willis, TX
Founded in 1870 and named for landowners P. J. and R. S. Willis, this Montgomery County town boomed when the Houston & Great Northern Railroad arrived, boasting a college, an opera house, and stores. By 1895 it was ringed with tobacco fields feeding seven cigar factories—an industry that collapsed when tariffs on Cuban tobacco were lifted, leaving timber and livestock as its mainstays.
The Railroad in Montgomery
Montgomery, TX
Frustrated by the difficulty of hauling crops to market, Montgomery businessmen organized the Central and Montgomery Railroad in 1877, and by 1880 a 25-mile line linked the town to the Houston & Texas Central at Navasota. The combined depot became a hub of local life—even the county jail was parked in the rail yard after the county seat moved away in 1889. The Gulf, Colorado & Santa Fe bought the line in 1882 to reach East Texas timber, extending the rails until a spot west of town became known simply as 'The Junction.' Passenger service ended in 1951, and the track into town was eventually pulled up.
Spring
Spring, TX
Platted by the Houston & Great Northern Railroad in 1873, Spring began as a farming community and quickly became a commercial hub and a center of German settlement, with figures like Carl Wunsche shaping its early growth. A new rail line and roundhouse in the early twentieth century turned it into a bustling rail and lumber town, complete with hotels, saloons, an opera house, and a bank. The loss of the roundhouse and the arrival of Prohibition thinned the town in the 1920s, but its school district and German heritage carried it into a renewed boom by the 1970s.
