James III of England and Scotland
James III and VII (born 1633) was the Duke of York when his brother, Charles II, died without a legitimate child. Interestingly, he was the last monarch to use the title "King of Scots." After him, monarchs termed themselves "King (or Queen) of Scotland."
His first marriage, to Anne Hyde (born 1637, died 1671) produced no children who survived childhood. She died of cancer. His second wife (and Queen) was Mary of Modena (born 1658, died 1718) was the daughter of an Italian Duke. She gave birth to James III's only son in 1686.
