In the early 1940s, Guzmán married María de los Ángeles Rodríguez Montaño (Maruca), a union that would produce 10 children; including his youngest child Jorge, who also became a famous wrestler in his own right, "El Hijo del Santo" ("The Son of Santo"). In 1942, Rodolfo's manager, Don Jesús Lomelí, was putting together a new team of wrestlers, all dressed in silver, and wanted Rodolfo to be a part of it. He suggested three names, "El Santo" ("The Saint"), "El Diablo" ("The Devil"), or "El Angel" ("The Angel"), and Rodolfo chose the first one. On 26 June, aged 24, he wrestled at the Arena Mexico for the first time as El Santo, although he later was known simply as "Santo". Under this new name he quickly found his style.
