The information I am trying to locate is my grandfather's Naturalization date...if in fact he was Naturalized, and his Italian birth certificate. His name was John Grimaldi (born Giovanni and changed to John) on April 15, 1907 in Sessa, Italy. He lived in Hartford, Connecticut all his life (as far as I know) and died there January 2, 1981. I also think his father (GGF) was named Giovanni Grimaldi and born sometime between 1866 and 1870...I don't know for sure where in Italy, but I'm guessing Sessa, Italy. His mother (GGM) was named Nunzia Sabatino Grimaldi and she was born in 1871 and I'm also guessing Sessa, Italy.
Any information or how to go about locating it would be appreciated. Do I need exact information about my great grandparents in order to locate my grandfather's Italian birth certificate (that probably sounds dumb and self evident


Thanks
