I have an interesting story regarding one of my Texas ancestors and William "Billy" Barton (owner of springs and apparently, slaves). I'm a direct descendant of Gen. Ed Burleson (from Republic of Texas fame). William Barton's son, Wayne Barton, married a daughter of General Ed. William Barton was the first Sherriff of Travis County. There was a dispute between the Burleson son (John) and William Barton and Barton shot and killed John. A couple of years later, two of John Burleson's brothers found William Barton and killed him.
edited to add that my GGG Grandfather, David Crockett Burleson (1837 - 1911) would have been about 12 years old at the time.
AUSTIN COLONY PIONEERS, Ray, 1995 Wayne Barton, son of old Billy Barton, was a waggish fellow with a strong sense of humor, says Noah Smithwick in his "Evolution of a State." (Because of his temper and because of his inherited dislike of neighbors... and perhaps because he had killed a son of Gen. Edward Burleson in 1848, two of Gen. Burleson's sons went after and killed him.. after numerous rounds were exchanged, despite the fact that Wayne Barton was the husband of their sister, Mary.)
NORTHERN STANDARD, of Clarksville, February 3rd, 1849, p.2, col.5: "Wayne Barton was killed in Washington County by two sons of General Burleson. Several shots were fired on both sides. Mr. Barton was a son-in-law of General Burleson, the former Vice-President of Texas. The quarrel originated from an old grudge - Barton having killed a brother of the Burlesons last year, and this was the first opportunity they had of taking revenge."
