If your Dad died during the war or later as a result of injuries received during the war, there is an organization for you. It is a legitimate (501 C 3) non-profit and its name is American World War II Orphans Network (AWON). Annual dues are nominal (and tax-deductible). To date there are approx 2,400 members, but children eligible may number as high as 130,000.
Please note that this is NOT a solicitation for money. I am just a member interested in spreading the word...
Drop me a note if you're curious.
