Hello,
I was looking at your post and I am looking for my family members as well. I am also looking into family members during the time of the Vietnam War. I was wondering if there is anything you can help me with in order to find my family members. Also, I know that this website may be extremely helpful !

Last but not least, you should look into the Census as well !

Best Wishes To You !

Sincerely,
