Selkirk Island

🏛️The era

When William Selkirk arrived in 1822, Texas was not yet American soil, and only barely Mexican. Mexico had just won its independence from Spain in 1821. The new government inherited a huge, thinly settled northern frontier that it struggled to hold against Comanche raids and against the ambitions of the United States to the east.

Mexico's answer was colonization. Under the empresario system, a contractor was licensed to bring in a set number of settler families. The families received generous grants of land, and in return they agreed to become Mexican citizens and obey Mexican law. Stephen F. Austin took over his late father's plan and became the first and most successful of these empresarios. The first families he brought in are remembered as the "Old Three Hundred."

The Texas they found along the lower Colorado River was hard country. The coastal prairie was flat and the river bottoms were thick with timber. The rivers were the roads, but they were often choked, flooded, or unpredictable. Native nations still controlled much of the interior. In those early years every settler was at once a farmer, a frontier soldier, and a living test of whether Mexico's experiment would work.

👥People & events

William Selkirk came from New York, and he brought more than a plow to Austin's colony. He was a surveyor, and surveyors were among the most valuable people on the frontier. A land grant meant little until someone ran the lines, set the corners, and turned a promise on paper into a boundary on the ground. Selkirk helped do that work for the colony, which put him close to the colony's beginnings.

Like other able-bodied colonists, he also served in the colonial militia. In 1824 Austin sent him with a group to make a treaty with the Waco and Tawakoni. These related peoples lived to the north along the Brazos and were part of the wider Wichita family. Austin's colony was small and exposed, and it depended on keeping the peace with its neighbors at least as much as on force of arms. That mission is a reminder that diplomacy, not just settlement, shaped those first years.

Selkirk's own reward was the land grant along the Colorado. It was among the first the Mexican government issued to American colonists in 1824. The land was a strange tract, split into several islands by the river's branching channels. A great log raft of fallen trees jammed the river near his property and blocked boats from going inland for years. Over time a sawmill stood near where Mill Creek once met the river's old eastern bed. A legend also settled over the place: one of Jean Lafitte's pirates, it is said, buried treasure at the north end of the island. Nobody has proven the legend, but Lafitte's men really did sail this coast, working out of Galveston Island in the years just before Austin's colonists came.

Selkirk died in 1830, still a young man by today's standards. The land did not leave his family. His descendants held onto it and went on to become civic and business leaders in Matagorda and Galveston counties. That kind of unbroken family continuity is rare anywhere and especially rare in Texas.

🇺🇸Its place in the American story

The Old Three Hundred are where Anglo-American Texas begins. They came as invited guests of Mexico, on Mexican land grants, under Mexican law. Within a little over a decade, the tensions between those settlers and the Mexican government led to the Texas Revolution, a short-lived republic, annexation by the United States, and a war with Mexico. That chain of events redrew the map of North America. Selkirk Island sits at the very first link in that chain.

Selkirk's career also shows how American expansion worked in practice. Expansion was not only armies and treaties between nations. It also meant surveyors running lines through river bottoms, militia companies, and small diplomatic parties riding out to Native towns. The Waco and Tawakoni mission is a small window onto a larger truth. The newcomers depended on Native peoples whose land, power, and futures would be badly reduced in the decades that followed.

The river itself tells a national story too. Log rafts like the one that blocked the Colorado were common on Southern rivers, and clearing them was a major engineering challenge of the 1800s and early 1900s. Later dredging reshaped the channels until Selkirk's islands joined back into solid ground. Here the landscape changed under human hands as much as the borders around it did.

🧭If you visit

Selkirk Island is in the low, wide country of lower Matagorda County, near where the Colorado River approaches the Gulf. Expect flat coastal prairie, big skies, and the damp, salty air of the bay country. The marker honors land the same family has held for two centuries, so treat the property as private and do your exploring from public roads.

As you stand there, try to picture the land the way the marker describes it. Several islands were cut apart by moving river channels, and a jam of fallen trees choked the river so boats could not get through. Those channels are now closed, and part of the old riverbed has gone dry. Reading the land for clues to the old river is part of the fun.

And yes, there is the pirate legend. It makes a good story for kids in the back seat. Just remember it is a legend, and the island is not open for treasure hunting.

This stop pairs well with a slow drive through Matagorda County's coastal communities and its bird-rich wetlands. If you are tracing Texas's founding, it works as an early chapter in a road trip through the old Austin colony lands along the Colorado and Brazos rivers, where the story of the Old Three Hundred is told again and again.
