I've never heard of anyone else in connection to cecile in that way...but anyone feel free to correct me. However i'm sure there was someone else i read about..perhaps in a book about the mountbatten of burma, in connection to Georg Donatus in this way but only briefly...anyone know any more about that perhaps?
As far as the prince philip thing goes, i don't know, i don't think that anyone would think of someone they've lost everyday if that person died 70 years ago, especially at his age, he was quite young himself when she died, but i also think he's a proud family man and can well imagine him making quite sure that her name would be known.
I don't really see any resemblance between philip and his sister, does anyone else?
