Humphrey Jackson
Crosby, Harris County, Texas
Marker Inscription
(November 24, 1784 - January 18, 1833) Educated in law, Humphrey Jackson left his native Ireland in 1808, during a period of political conflict. He migrated to the United States and settled on a sugar plantation in Louisiana. While there he served in the 1815 Battle of New Orleans. Unable to manage his plantation without the use of slavery, which he opposed, Jackson sold his land and came to Texas in 1823 to join Stephen F. Austin's colony. Not realizing he was locating outside the colony's boundaries, he settled on land at this site. when the error was discovered, he joined other area settlers in successfully petitioning the Mexican government to form the San Jacinto District under control of the Austin colony. Jackson was elected to serve as alcalde of the new district. One of the pioneer settlers in present Harris County, Jackson was active in the early local government. His efforts on behalf of the surrounding settlement and his ability to mediate disputes impartially led to further development of the area. In 1833 Jackson was killed by a falling tree while clearing his land. Twice married, he was the father of four children. His descendants include prominent business, professional and political leaders.

The Story
Trained in law and opposed to slavery, Irish emigrant Humphrey Jackson left his Louisiana sugar plantation to join Stephen F. Austin's colony in 1823, unknowingly settling just outside its bounds. He helped petition Mexican authorities to form the San Jacinto District under Austin's control and was elected its alcalde, becoming one of the earliest civic leaders in what is now Harris County before his death in 1833.
Why it matters
Jackson's story captures the immigrant roots and improvised local government of the Anglo colonists who first settled Mexican Texas.
The story behind this marker
AI contextThe era
When Humphrey Jackson arrived in 1823, Texas belonged to Mexico, and Mexico had only just won its independence from Spain. Hoping to settle its sparsely populated northern frontier, the Mexican government allowed empresarios like Stephen F. Austin to bring in American families in return for land grants and loyalty to Mexico.
The land around the lower San Jacinto River, in what is now eastern Harris County, was wooded, well-watered frontier. Settlers there were building farms from scratch with axes, oxen, and a lot of backbreaking labor.
This was also a time of intense debate over slavery. Many Anglo colonists brought enslaved people into Texas even though Mexican authorities were uneasy about the practice. A settler who opposed slavery, as Jackson did, stood out among his neighbors.
People & events
Humphrey Jackson was born in Ireland in 1784 and trained in the law. In 1808, during a period of political conflict in his homeland, he left for the United States. He settled on a sugar plantation in Louisiana, and in 1815 he took part in the Battle of New Orleans, the famous American victory over the British at the end of the War of 1812.
Louisiana sugar farming depended almost entirely on enslaved labor, and Jackson opposed slavery. Unwilling to run his plantation that way, he sold his land and set out for Texas in 1823 to join Austin's colony. He did not realize the land he picked here lay outside the colony's boundaries. When the mistake came to light, he and other settlers in the same position petitioned the Mexican government and won the creation of the San Jacinto District under the Austin colony's control.
His neighbors elected Jackson alcalde, an office in Mexican local government that combined the duties of mayor and judge. He earned a reputation for settling disputes fairly, and his leadership helped the settlement grow. In 1833 he was killed by a falling tree while clearing his land, a very frontier kind of death. He married twice and had four children, and his descendants went on to become leaders in business, the professions, and politics.
Its place in the American story
Jackson's life ties together some big themes of early American history. He was an immigrant fleeing conflict in Ireland, a veteran of a battle that became a point of national pride, and one of the Americans who moved into Mexican Texas in the 1820s, a migration that would change the map of North America within a generation.
His story also shows how self-government actually worked on the frontier. Settlers who found themselves outside any clear jurisdiction did not simply ignore the law. They petitioned the government, formed a district, and elected one of their own to keep the peace. That habit of local organizing would matter a great deal in the Texas Revolution a few years after his death, which ended near the San Jacinto River in 1836.
Finally, his decision to walk away from slave labor is a reminder that the Anglo settlement of Texas was not uniform in its values. Most colonists accepted slavery. Some, like Jackson, would not, and that makes his choice worth remembering.
If you visit
The marker in Crosby puts you close to the land Jackson cleared nearly two centuries ago. The area today is suburban and rural east Harris County, but the San Jacinto River and its wooded bottomlands still suggest the country the first settlers knew.
As you stand here, think about how much of the Houston region's story began with small clearings like this one. Families like Jackson's were working the ground before Houston existed, well before the city's growth swallowed up so much of the old frontier.
For a fuller day, combine this stop with the San Jacinto Battleground to the south, where Texas won its independence just three years after Jackson's death. Together the two sites trace the arc from Mexican colony to independent republic.

de Zavala Plaza
San Jacinto, TX
This plaza honors Lorenzo de Zavala, the Yucatán-born liberal who was jailed for years for his politics, taught himself English and medicine in prison, and served in the Spanish Cortes and as a Mexican governor before opposing Santa Anna's dictatorship. Loyal to Mexico's 1824 Constitution, he moved to Texas, signed its Declaration of Independence in 1836, and became the Republic's first vice-president; he, his descendants, and neighbors lie in the family cemetery across Buffalo Bayou.
Crown Hill Cemetery
Pasadena, TX
As permanent settlers arrived near Buffalo Bayou in the 1890s, the new town of Pasadena needed a place to bury its dead, and this knoll overlooking Vince's Bayou became its community graveyard in 1906. Renamed Crown Hill after World War I, likely for the nearby Crown Central Refinery, it holds veterans of four American wars and generations of early settlers and community leaders. It also became a resting place for Mexican-American farm families beginning in the 1920s, earning it the name the Mexican Cemetery.
Lorenzo de Zavala
Houston, TX
Born in Mexico in 1789, Lorenzo de Zavala was a statesman of two nations — a liberal reformer who served in the Spanish Cortes, as Mexico's treasury minister, and as ambassador to France before Santa Anna's tyranny drove him to Texas in 1835. There he threw himself into the cause of independence, signed the Texas Declaration, and became the Republic's first vice-president; his home near the San Jacinto battleground served as a hospital for both sides after the fighting.
Humphrey and Sarah Merriman Jackson
Crosby, TX
Humphrey and Sarah Merriman Jackson came to Texas in 1823 as members of Stephen F. Austin's "Old 300," settling east of the San Jacinto River. Their land grant helped open the San Jacinto District and enlarge Austin's colony, adding fresh ground for Anglo settlement. Sarah died just a year after arriving, and the couple lies buried nearby beneath a distinctive zinc grave marker.
