The favourites and odds for the baby’s name

Arthur

A middle name of the Prince of Wales, the Duke of Cambridge, and George VI, the Queen’s father. Harks back to King Arthur, the mythical leader of the knights of the Round Table.

2/1 Philip

A lasting tribute to the Duke of Edinburgh might see a Prince Philip of Cambridge. Both Prince Charles and Prince William have Philip as a middle name.

5/1 Frederick

Prince Adolphus Frederick, the first Duke of Cambridge, lived from 1774 to 1850 and was a son of George III. He was apparently very fond of interrupting church services by bellowing out “By all means” if the priest said “Let us pray”.

16/1 Charles

Prince William may want to pay tribute to his father – but perhaps as a middle name, as it may be considered too similar to Charlotte.

25/1 James

James could be chosen to signify the Duchess’s affection for her brother, James Middleton. William has a cousin James, Viscount Severn. Looks back to two kings, and five earlier kings of Scotland

4/1 Other names

The couple could choose William, but also perhaps Michael, out of respect for the Duchess’s father. Her grandfathers were called Peter and Ronald. Thomas also appears several times in the Duchess’s family tree as does Francis.
