Samuel Augustus Maverick (1803-1870) was born in Pendleton, South Carolina, the son of Samuel and Elizabeth (Anderson) Maverick. His father was a plantation land owner. He was a Yale graduate and followed his father's interests in real estate development. He studied law, practiced for a while in Virginia, ran for office unsuccessfully in South Carolina and moved to Texas in March 1835 after spending some time in Georgia and Alabama. He arrived just in time to be caught in the Texian struggle for independence. Present in San Antonio during the Siege and Battle of Bexar he was under house arrest with John W. Smith and A. C. Holmes. They were released and joined the Texians and were influential in guiding the final attack. Maverick remained in San Antonio after the Texian victory, was a member of the Alamo garrison when it became under siege from Mexican centralist forces under Santa Anna in March 1836. He departed the Alamo on 2 March to attend the Texas independence convention at Washington-on-the-Brazos. Suffering from an illness, he was unable to actively participate thereafter and departed for Alabama before or at the time of the Battle of San Jacinto. Back in Alabama, Maverick married Mary Ann Adams in August 1836 and they returned to Texas in summer 1838 eventually settling in San Antonio where Maverick practiced law and served San Antonio both as mayor and other offices. Maverick was taken prisoner upon the invasion of San Antonio by general Adrian Woll's forces and was one of the Perote prisoners released in 1843. He returned to serve in the Republic of Texas Congress. For a period the family resided on Matagorda Bay, but eventually returned to San Antonio where he continued to serve in the State of Texas legislature and in local government. Historically against secession in concept, Maverick remained loyal to the State as it joined the Confederacy. Maverick's land holdings became extensive during his life, particularly in West Texas totaling about 300000 acres at his death. When Maverick returned to San Antonio from the Matagorda Peninsula, he left herds of cattle ranging freely on the rugged coastland that were periodically rounded up, branded and driven to a family ranch near Floresville. It is believed that the term maverick referring to unidentified, unbranded cattle originated from the Maverick surname. Maverick died in 1870 and Maverick County, Texas is named in his honor.
