Royal dukedoms are short lived

"Where is Bohun, where's Mowbray, where's Mortimer? Nay, which is more and most of all, where is Plantagenet? They are entombed in the urns and sepulchres of mortality." Lord Chief Justice Sir Ranulph Crewe in his judgment in the the Oxford Peerage Case 1625.

The title Duke of York is traditionally given to the second son of the King of England or later Great Britain.

Kings Edward VI, Henry VIII, Charles I, James II (after whom New York is named), George V and George VI were Duke of York before ascending the throne.

The title Duke of York  has been created eight times in English history and the title Duke of York and Albany has been created three more times but curiously the previous creations all became extinct. 

So have oddly have all the royal dukedoms, from the first creations of Edward III until those of King George V, except for the two which were held by German members of the royal family.

The Duke of Cumberland and Teviotdale and the Duke of Albany were deprived of their titles in 1917 for fighting against King George V. There are heirs to these titles who could petition the King to be granted them.

There were Viking kings of Jórvík or York for much of the time between 867 and 954 and later Earls of York before the French title duke was adopted by King Edward III.
