Matthew Fielding Locke
After the war, Locke returned to Mississippi, and in 1849 married Elizabeth A. Biue. Shortly thereafter they moved to Upshur County, Texas. He established a plantation about 13 miles (21 km) northeast of present-day Gilmer and founded the nearby town of LaFayette (which he named after his son, LaFayette C. Locke, who was born in 1850). Locke began the first of two terms as a state representative in 1855 in the Sixth Texas Legislature. In the Seventh Legislature, Locke was elected Speaker of the House "pro tempore" on 26 December 1857 when Speaker William S. Taylor took ill. When Taylor resigned on 18 January 1858, Locke was elected Speaker over Reps. Isaac N. Dennis and John Henry Brown, 39 votes to 14 and 13, respectively.
