Theatre Orchestra, New Orleans Beginning late-November-early-December 1918, De la Mora worked as a musician in New Orleans in the Concert Orchestra under the direction of Don Philippini (né Salvatore Philippini; 1870–1950) of the recently built Strand Theater. The Strand, no longer in existence, was at the corner of Baronne and Gravier Streets for about 53 years. On February 9, 1919, de la Mora seemingly tried to commit suicide by leaping eighteen feet to the street from the second-story window of the newspaper editorial room of the New Orleans States building at 619 Canal Street. News accounts attributed de la Mora's distress to a prior nervous breakdown from overwork and marital unhappiness relating to disagreements with in-laws. De la Mora, about two months earlier, had married Susan May Stennis (maiden; 1899–1973) in Meridian, Mississippi. Soon after marrying, they moved to New Orleans and resided at 611 St. Charles Street (at Lafayette Square). Wichita, Kansas In 1925, Antonio de la Mora was living in Wichita, Kansas, at 1665 North Waco Avenue with his wife, Martha, and two sons, Antonio, Jr., and Adolphus. He was working there as a music teacher. He resided with his family at 2239 North Laurel Street. Kansas City, Missouri De la Mora moved to Kansas City, Missouri, around December 1925 to organize the Mexican Band of the Unión Cultural Mexicana (U.C.M.) in Kansas City's Westside at 1017 West 24th Street. He trained a 45-piece band composed mostly of youth from the community. De la Mora, with Martha (1903–1983), Antonio, Jr. (1922–1985), and Adolfo (born 1934) – his wife and two sons – resided at 2322 Monitor Place. The Mexican communities in Wichita and Kansas City were viewed somewhat as colonies for Mexican exiles. Death in Kansas City, Missouri Antonio de la Mora died May 9, 1926. Dr. Nicolás Jaime (1885–1965) (surname pronounced "high-me" with the accent evenly divided) was the attending physician who signed the death certificate. He and Dr. Othoniel de Rivas y Jaén (1890–1973), a Granada, Nicaragua-born chiropractor, held a funeral vigil for Antonio de la Mora May 22, 1926, at the U.C.M. Dr. Jaime, a co-founder of the U.C.M., days earlier had signed a US$2,500 bail bond () for Jorge Prieto Laurens (1895–1990), who was elected and served as interim governor of San Luis Potosí in 1923 for one year, was indicted in San Antonio and arrested on February 28, 1926, in Kansas City, on
