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 non-profit and its name is American World War II Orphan's Network (AWON). Annual dues are nominal (and tax-deductible). One advantage of being a member is that the Network has information and resources to aid in finding out about your father. To date there are approx 1,900 orphans registered, but children eligible may number as high as 150,000.
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.
