WOW, THANK YOU!!!!
I know NOTHING of William, other than his name, and that was only through the help of this message board! (well, that goes for the whole family for that matter)
From the information you have, it looks like 4 of them were put up for adoption. We knew 2 of the girls were, DeEtte- my grandmother, and I don't remember off hand what her sister's name was. I only met her 2x that I know of, when I was really young.
I really appreciate your information.
