Frank and Ventura Alonzo (husband and wife) were longtime residents of Houston and Magnolia Park, and were big band musicians from the 1930's until they retired in the late 1960's. Originally fron San Antonio, Texas, and Matamoros, Tamaulipas respectively, they met in Houston and married in 1931. Discovering a mutual love of music, they began their first band in the late 1930's and played for local gatherings in Magnolia Park. Frank played guitar and Ventura played the accordian. Their orchestra developed into "Alonzo y Sus Rancheros" during the 1940's with Frank as the leader and Ventura as lead vocalist. From the 1940's through the 1960's the band was popular in Houston as well as in many other areas of Texas where they travelled to perform. They specialized in música ranchera, a form of music from Texas roughly equivalent to a Mexican American country western sound. Over these three decades few Mexican American dance bands enjoyed the popularity and acclaim of "Alonzo y Sus Rancheros".
