Marilyn Monroe's mother was born in Piedras Negras, Mexico.

"Marilyn Monroe, discreetly, embraced her Mexican heritage, which she kept secret from the public. She became conversant in Spanish, though not fluent, a fact that made handlers at 20th Century Fox nervous; on her many trips to Mexico they wanted her to pretend she didn’t understand the language, lest there be a newsreel of her speaking Spanish, an event that would spoil the fantasy of who she was to the American people."
