Mercedes History

This region was originally settled by ranchers in the late 1770s. It was a part of the Llano Grande Spanish land grant that was issued to Juan José Ynojosa de Balli on May 29, 1790. For a major part of the 19th and early 20th century, the area was owned by the family of Ramón and Manuel Cavazos. The Capisallo Town and Improvement Company was formed by Lon C. Hill, Jr. on May 29, 1904, and he developed a community which was named "Lonsboro." Hill's company was taken over by American Rio Grande Land and Irrigation Company, and they renamed the community "Diaz." This name was changed a few times until the area was christened "Mercedes". According to some records, this name was in honor of Mercedes Diaz, the Mexican President Porfirio Diaz's wife. The city was officially established on September 15, 1907, and incorporated on March 8, 1909.
