The largest land grant in South Texas, the San Juan de Carrictios lands were awarded to Don Jose Narciso Cavazos in 1792 by the King of Spain. Comprising over one-half million acres, the grant included virtually all of present Williacy County, including the sites of the towns of Sebastian, Lyford, Raymondville, Lasara, San Perlita, and Port Mansfield. In 1793 Cavazos took formal possession of the land grant seven miles north of this site. Most of the grant was later sold by Cavazos' heirs, although some descendants still live within its boundaries. (1988)
