Hi Carole, Thanks for the reply. I don't know where I'd find the district number. But the ppl I'm looking for were Joseph and Rose Volpi, my g-grandparents. They lived (and died) in Oakland in 1948 (Rose) and Joe in 1951. They lived on Campbell St. I hope to find out if they were naturalized citizens, both were born in Italy and emigrated here at the utrn of the last century. This is my first step in sending away for their naturalization papers. Thanks for any help. Linda in N/Cal.
