Regarding my wife's maiden name Alba. Her father is Paul Alba, born 1919 in Cuba GrandfatherLeonardo Asuncion Caballero Montes Alba, born in Camajuani, Cuba, inMilitary, emigrated USA in 1919. GGrandfather Leonardo Montes Alba, born in Rute, Spain. Apparantly left Rute to establish himself in Spanish possession of Cuba where the family hard a large plantation until Castro's rise to power. There is no family tree showing link to the Duke, but it has been part of family lore forever. My efforts to find a list of descendants of the Duke have not succeeded, so it stays unproven. There is a Duke of Alba brandy however that has a picture of the Duke on it. It is like looking at my wife's brother, the resemblance is so exact.
