I don't know these people but gave it a try anyway. I copied the 1961 city directory for doctors and the dentist to be on the safe side. We have the actual marriage books in our library and I went through 3 of them, covering both sides of that 1961 date and never found any doctor's surname with a daughter by that name. We have no access to the birth records and chances are if someone don't know the family, you may not find this brother. Don't give up, it took me over 20 years to find mine, if people don't want to talk, you won't hear anything. I copied the city directory for you and have no way to send it because I don't have your e-mail address, this directory might help you some day.
