He moved to Texas in 1859 and built a home across from the courthouse in San Marcos. He practiced law with E. Kone. and later with the firm of Hutchison and Franklin. On October 10, 1861, near Austin, William married Leonora Shields Clifton (December 2, 1838-June 8, 1903), who had been born in Terrebone Parish, Louisiana. They had three sons.
