Kahlo's father, Guillermo Kahlo (1871–1941), was born Carl Wilhelm Kahlo in 1871, in Pforzheim, Germany, the son of Jakob Heinrich Kahlo and Henriette Kaufmann. Kahlo's mother, Matilde Calderón y González, was a devout Roman Catholic of mixed Amerindian and Spanish ancestry.

Sorry to disappoint the La Raza Unida bunch but truth is Mexico is made up from MANY different ethnicities just like the USA.
AND SHE WAS AN ADVOCATE OF TROTSKY-STYLE COMMUNISM WHO HAD AN ADULTEROUS AFFAIR WITH LEON HIMSELF.
But what can you expect of an savant who painted mainly self-portraits...
