Scattered all throughout Europe are trunks and chests full of treasures; of this I am certain. When something like this is examined, the question I always want to know is, what's missing? What were the really valuable items that ended up being pawned off during the war (s) and what was filched out of there by a thieving relative?
Items from two or three hundred years ago are commonplace enough in small museums in Germany; really, you can go to any stadt museum and see excellent pieces. I'm sure it's that way throughout the continent; maybe not, but I suspect that there are trunks needing a good dusting all over. Perhaps that is oversimplified and overly romantic.
In America, if it's a hundred and twenty years old or more, people lose their mud over such an "antiquity." The American way is to tear it down, pave it over, get rid of it. We do not preserve much of anything in this country.
To call Napoleon's sister a princess is to acknowledge her marriage to a man of limited title who abandoned her for a mistress; she became Paulette when the family arrived in France and was loyal to her brother to the end of his days.
I think that the article should have reflected more of her status as a wholly created royal with the same commoner's blood as her brother. If you consider the painting above, someone had to have been cruelly inclined to give her too long of a neck. What an unflattering portrait.
