My surname is Giachin, I live in Italy where all the Giachin and Giachino family are from. I think maybe you're searching someone named GIACHIN RICCA because this is a very common version of this surname (though there'are many Giachino too). The origin of the family is in a little area in Piedmont, Italy. I know some Giachin Ricca still living here, but I don't know about their relatives emigrated to America. I'll look for further info as soon as possible.
