William III entry:
"...On 4th November 1677 William married his cousin, the Princess Mary (born 30th April 1662), elder daughter by Anne Hyde of the Duke of York, afterwards James II.---a political match, which did not at first prove a happy one. Until the birth of her half-brother on 10th June 1688 Mary was heir to the English crown."
William III "was the posthumous son of William II. of Orange (1625-50) by Mary (1631-60), the eldest daughter of Charles I. of England".
So, in 1677 Charles I's daughter's son (age 27) marries Charles I's son's daughter (age 15). They are first cousins.
