Hi, my mother had a child in late July 1958 Chicago. That baby girl was adopted in early August through Lutheran Social Services.
The details I have are sketchy, but they are:
Adoptee: Birth Name Ingrid Anne, DOB 7-30-1958, adopted 10 days later
Adopted family: father has his own business; both parents interested in education; they also have an adopted son about 3 yr. older
And that's it! My mom left her contact info with the agency in case the girl ever wanted information, but she was never contacted.
