A portrait, believed to be of the Duke of Cambridge, or possibly Henry Valentine-Green, 2nd Baron Green of Earby.
John Vasa, 2nd Duke of Cambridge (1583 - 1675) was an English nobleman, and a member of the English branch of the Swedish royal House of Vasa. He was considerably influential. He was the son of John, Duke of Cambridge. He remained single for most of his life, until, according to his brother, he fell in love with and married Mary Boleyn. He died from a heart attack, apparently during an act of physical exertion in bed with his mistress. He was succeeded by his son, Eric Vasa, Duke of Cambridge.
