For a Princess: Mary
Mary would be a fitting tribute to the Royal ladies named Mary.
Mary would also be a fitting tribute to Catherine's paternal side of the Middleton.
She has three ancestresses named Mary Middleton.
I agree. Not even to mention the fact that HM and Philip named their firstborn Charles well aware of the somewhat unfortunate history of that name. If William and Catherine have to rule out all names who have the slightest negative connotations attached to them, they would barely have any names left to use.
Archduchess Zelia, this is a grand observation.
If Prince William and Catherine have a son and name him John, John shall be his name.
William Arthur and Catherine Elizabeth are the parents.
Hopefully the general public has not forgotten this fact.
For a Princess: Marjorie
Marjorie (1297-1316) was the daughter of King Robert I of Scotland.
She married Walter the Steward.
Their son became King Robert II of Scotland.
Princess Joan.
Lady Nimue, Princess Joan is an excellent choice!
Princess Joan, daughter of King John of England became Queen Joan of Scotland from 1221 to 1238.

For a Prince: Walter could be used as a middle name.
Walter, 6th High Steward of Scotland, was the father of King Robert II of Scotland.
Robert II and Walter are ancestors of Queen Elizabeth The Queen Mother.
For a Princess: Georgiana could be used as a middle name.
Suppose the second child is a daughter.
The first name of the Princess is announced: Eleanor.
We ask: Why was Eleanor chosen?
We speculate and scrutinize: After Queen Eleanor and/or Princess Eleanor.
We ask: Eleanor of Aquitaine, Eleanor of Castile, Eleanor of Provence, Eleanor of Brittany?
