Roger Cadiere

I am a resident of the USA in Connecticut. My father was Jean Marcel Ciarrier (or Cadiere) of Marseille. My Grandmother was Fanny Rivoire (or Rivora) of Torino De pelice (?) in Italy. She arrived in America with my father about 1908 and worked for the family of the world famous actress, Katharine Hepburn, for all of her life. My family and I are trying to locate members of our French family. We have little information except that they lived in Marseille at the Rue De Sollier and my Grandmother may have spent time in Algeria. I have a picture of a relative named Roger Cadiere who was a soldier stationed in Allemagne. Any help will be greatly appreciated. John
