Diego Columbus

He was born in Portugal, either in Porto Santo in 1479 or 1480, or in Lisbon in 1474. He spent most of his adult life trying to regain the titles and privileges granted to his father for his explorations and then denied in 1500. He was greatly aided in this goal by his marriage to María de Toledo y Rojas, niece of the 2nd Duke of Alba, who was the cousin of King Ferdinand. Provided by Wikipedia
