Roger, First thank you for serving our country. As for your quest for help. I was wondering if you have tried www.military.com and searched there for some of those you are looking for or posted a message like you did here, it might be helpful.Also are you aware that the NARA had put up some enlistment records for WWII Army units. Just incase it might be helpful to you the web address is as follows; http://aad.archives.gov/aad/search.jsp?file_id=3475&coll_id=null&data_layout_id=494&table_id=893http://aad.archives.gov/aad/search.jsp?file_id=3475&coll_id=null&data_layout_id=494&table_id=893
This address will take you to a search where you might find information on those you are searching for, at least a home of record and a year of birth.
Another idea for to possibly verify those names you have but yet to find them alive or deceased. There is the Social Security Death Index, it's good if you have a name nad possible year of birth, that database can be reached thru the following link;http://ssdi.rootsweb.com/http://ssdi.rootsweb.com/
