> Well French isn't a bad guess, is it, considering she moved to France, married a Frenchman, became a French citizen, took his French name and probably spent most of her life in France?
You make it sounds like she did it out of choice, like someone who would take a nationality out of kinship, but the reason why she moved to France have little to do with French sympathies but more prosaic reasons:
> After Russian authorities [Poland was partly controlled by Russia at the time] eliminated laboratory instruction from the Polish schools, he [MC's Father] brought much of the laboratory equipment home, and instructed his children in its use.[11]
> Unable to enroll in a regular institution of higher education because she was a woman, she and her sister Bronisława became involved with the clandestine Flying University, a Polish patriotic institution of higher learning that admitted women students.[10][11]
> Maria made an agreement with her sister, Bronisława, that she would give her financial assistance during Bronisława's medical studies in Paris, in exchange for similar assistance two years later.
Also, as per wikipedia:
> While a French citizen, Marie Skłodowska Curie (she used both surnames)[6][7] never lost her sense of Polish identity. She taught her daughters the Polish language and took them on visits to Poland.[8] She named the first chemical element that she discovered—polonium, which she isolated in 1898—after her native country.[a]
That's interesting, but I wasn't making any insinuation about why she became French. I was simply giving reasons why "French" wasn't an unreasonable guess for people to make.
