Attic find

Dh was up in the attic this morning running some wiring for Bella's light and came across a box of old paperwork. Inside we found a Navy recruit ID card and 2 photo ID Liberty Cards along with savings books, bank statements, pay stubs and other paperwork from the previous owner. I know this is a piece of history and this man served our country during the war (WWII). I haven't been able to find any info online though to get it back to his family. I was told to go to Ancestry.com and I posted a found notice there. If you know anyone with this surname, pass it on. Maybe they are a relative!
