I'm Chave's oldest son, and I was just looking over my grandfather's book which includes my mother's story/adoption, etc.. It mentions a few details and several different leads/agencies that may be of significance to follow up on for my mother's search for her family. Some details even that my mother mentioned she wasn't aware of/didn't recall. So if you can contact me directly via email and provide me with your contact details/phone no. that would be of help.
