If someone emigrated in 1912 and came through Ellis Island, the best place to find his place of birth is on the manifest. It would be a good to know the approximate age of the immigrant and if he was married or single at the time. So, when checking the Ellis Island web site for Salvatore Dilluvio, there actually are several entries. Maybe you have already checked this web site and couldn't actually find the right person based on the information you have. There is a good chance he came from Borgetto, Palermo, Sicily. But, you would need to actually find the correct Salvatore Dilluvio to be sure. If you are unable to find him, it could be due to a transcriber's error in the spelling of the last name. I like using the Steve Morse search form for Ellis Island, because of the versatile ways to search. Here is the site, in case you do not know it: http://stevemorse.org/
The manifests in this time period (circa 1912) provided some great information, such as name of nearest relative back home, final destination, the name of the person at the final destination, occupation, married or single and place of birth, to name a few.
