Hi, I'm trying to find information on Princess Anna (Lubomirska) Radziwill of Poland in order to settle a long-standing weirdness in my family tree. She has a profile on this site, but no information about parents or siblings which is what I need to determine if she's a relative of mine.
The supposed connection is this: My grandmother claimed to have an aunt who married a "Prince Janusz Radziwill". Their son, Stanislaw Radziwill then married Caroline Bouvier (Jackie Kennedy's sister).
But, my grandmother's account of this was shaky. She was born in Poland in 1926, and was 13 when WWII broke out and she lost her home. By the end of the war, she was in Kenya, by way of a Russian prison camp, an Iranian hospital and a Tanzanian hotel. Her memories of her family are those of a young girl.
And there are issues with her account; Most notably, that her father's surname at birth was "Rawicz-Wroblewski" not "Lubomirski". But even without having these issues pointed out to her, my Grandmother's story always seemed to contain some form of explanation. For example, she said that she didn't know her aunts well because her own grandparents had some manner of split (Is this at all likely in early 20th century Poland?) and while her own Father was raised by her Grandfather, all the girls had been raised by her Grandmother.
It seems far-fetched to me, but she said this before being confronted with the discrepancies. And if she'd already done the needed to pre-emptively cover discrepancies like that, then she also didn't research a bunch of obvious things (like Caroline Kennedy's name).
In any case, I think I have enough information to make a determination if I can find out Princess Anna (Lubomirska) Radziwill's parents and siblings -- but I can't find that anywhere. Anyone have any thoughts on where to find information on the family of Polish aristocrats in the early 20th century?
