I'm guessing
1. Johnny Crotch-Thrust in the background beside the princesses is Murat?
2. Baldy behind Napoleon is one of the brothers and so is the hat wearer behind him.
3. Who is the marshal at the back of the group clutching the sword to his chest and holding his baton up? The guy giving him the incredulous look is another one I am interested in.
The foreign-dressed gentleman at the plinth could be Roustam, no idea who the cardinal is. Talleyrand used to be a priest and a bishop but I don;t knwo much about him.
The hats make it difficult to pick anyone of the marshals out, no red haired Ney or bald Davout - and they all look very similar too.
Turns out Napoleon had Josephine removed from this pic because he was about to divorce her.
