Unfortunately, I can't help you with you father's serial number, Deanna. One thing I did wonder about, though, when I read your message:
"My cousin is looking for the military records to be able to join VFW as her father, my uncle, was never in the service."
If I read this correctly, your cousin is seeking to join the VFW Auxiliary on the basis of your father's service? If that is the case, she might want to double check eligibility requirements. As a niece, I don't think she would be eligible. For more info, see this web page: http://www.ladiesauxvfw.com/http://www.ladiesauxvfw.com/
