The first charolais in the USA were bred up from a mix of longhorns and hereford. They came from mexico and the Pugibet herd.

Not quite try Brahman.
"In the late 1940s and early 1950s the breeders established the American Charbray Breeders Association and the American Charolais Breeders Association, both of which limited pedigrees to a blend of
Charolais and Brahman breeding. Producers who were utilizing other beef breed cows to produce Charolais by compounding Charolais blood through successive generations, formed the International Charolais Association. In 1957, the American and International Associations merged into today's American-International Charolais Association (AICA). In 1964, the Pan-American Charolais Association, whose registrations were based on performance rather than genetic content, merged into the AICA. And three years later, the American Charbray Breeders Association merged with the AICA, bringing all Charolais-based breeds in the United States under the fold of a single breed registry."
