I am searching for my husbands' father's birth mother.
He was born in Boise, Idaho April 14, 1931. Marvin and Iva Mae Casey adopted him when he was 1 day old and named him Merl John Casey.

His birth mother was said to be about 15 or 16 years old and from a prominent Boise family. The doctor that delivered him was Charles Sanford Allen. He also arranged the adoption.

Any guidance anyone can give would be greatly appreciated. We have already check with the Boise Children's Home and he was not adopted from there.
