Hi Lu

Welcome to AfriGeneas!

Am I clear when you say that the person was legally adopted once and somehow went back into the system and was legally adopted again?

If you check the link below, it is the link to the MD State Archives Reference & Research. It will give you information on getting information on adoption records in MD. Since the adoption took place before 1947, the records are open. The link will be able to help you further.
