This is an email I sent to the Ellis Island History Center on May 2, 2008, but I don't have a record of a response. The email is: history email@example.com
"I have been looking through your records for my grandparents who came from Italy through Ellis Island sometime between 1910 (when they were married in Italy) and 1915, when their oldest child was born in the US, but I have not been able to find them. I have done several types of searches on their names and their parents' names, but nothing has come up. Their youngest daughter, my aunt, their only remaining child who is alive, had given me their name spellings and dates."
