I wish I did know. Here is a little more info that might help in the search. He had a sister named Maxine/Betty. He had an older brother named David. There were a set of twins, Dan and Bryan(?). My Mom states, Bill may have come from Tennessee.
I have contacted the orphanage over the past years. I was told to write him a letter, mail it to them. If they have an address then they would mail it to him.
The current address that I have is:
P.O. Box 746
Columbus, Mississippi 39703
I did not follow through. I felt let down. But it's time to begin again.
Thank you everyone for your help
