You definitely have a unique situation, knowing your fostermom and having spent so much time with her - then coming back 40 yrs later.
I did find out my fosterparents names a few months back. I tried to locate them, but only had a last name, so it was just about impossible to find them in a huge city like charlotte. I looked them up in the 1970 city directory and called the one and only family with that name, but she said it wasn't her.
Turns out that in that short 8 weeks, I was moved to another foster home, because I was colicy and that mom couldn't handle it. Funny thing is, when I was moved, my stomach problems magically disappeared.
I have given up on ever locating them, as I feel I've learned what I needed to know. No point in hanging out in the past when there is nothing to find. I am at peace, finally.
Good Luck with searching.
