(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. (1982)
