My grandfather, Emanuele Marenco, son of Giovanni Marenco and Maria Delle Piane,of Varese Ligure, had 13 siblings. My grandfather and at least 2 of his brothers that I have identified, settled in San Francisco, California in the early 1900's. I don't know how many of the siblings immigrated to the US. I know of 3 including my grandfather, and I know that there was an older brother, Giuseppe, who remained in Italy. I'd love to hear from anyone who may be related!
