Hi, I am Serena and my family came to America right before World War 2.
The reason that this is significant (and might be for you as well) is that there is a grave records site for all the men and women who have died in World War 1 and 2.
It’s really easy to use and gives back good results that you can actually use.
Here it is: http://www.cwgc.org
Please share your best places where you can search and that really give you results.
Thank you, Serena Ponzio
