Franco was born in
Oviedo. Officially, Carmen Franco was the daughter of Francisco Franco and his wife, Carmen Polo. However, persistent rumors and historical research strongly suggest that she may have actually been the biological daughter of Franco's younger brother,
Ramon Franco and a prostitute who died after giving birth to her. On 10 April 1950, in
El Pardo, she married
Cristóbal Martínez-Bordiú, 10th Marquis of Villaverde. Villaverde was a prominent surgeon. In 1968 he conducted the first
heart transplant operation in
Spain. The couple had seven children: •

her father's death in 1975,
King Juan Carlos created her
Duchess of Franco and a
grandee of Spain, with a
coat of arms of new creation. The arms are a variation of the arms of the de
Andrade family of
Galicia, from whom she is twice descended from the Pardo de Andrade branch, and twice again from the 7th counts of Lemos and Sarria. ==Controversies ==
