Coming to France and afraid, what should I do?

I am Austrian, born in Vienna, and my family is rather important there (thought both of my parents, my father Francis and my mother Maria Teresa were born in Italy). I had great education, and can speak several foreign languages, French, too. I met and married a very distinguished Frenchman, and now I am moving to France. We already had one member of our family marry a Frenchman and move to France, it was long ago though. It was my great-aunt, Maria Antonia Josepha Johanna. She was not happy there and he and her husband died violent deaths. My grand-aunt and I share the one of our firsts names, too. I am going to Compi�gne, then we will celebrate our marriage in Paris, and then - back to Compi�gne. I should be happy and think about dresses and arrangements, but can't stop thinking about my great-aunt instead. There seem to be so many similarities between us: names, marriages, tastes. I feel as if something bad will happen in France to me, too, and almost do not want to go. I understand how silly it is but I can't help myself. What should I do?
