Lovely photos!
Antoinette was indeed Rainier III's sister. Pierre is the one with the short hair and Beatrice is his girlfriend. As far as I know she is still a law student/aristocrat.
Please forgive my ignorance. P. Antoinette was Prince Ranier's sister? Pierre is the one with the short hair correct and Beatrice is his girlfriend? What does Beatrice do, she looks like a ballerina.
