My Half-Brother

•  Born: 23.09.1960 (now 65 years old)   
•  Was adopted through Augustinusstift / Sozialdienst katholischer Frauen e.V. Bergisch Land / Caritas

Possible places of residence : 

•  Ghana or Africa 
•  United Kingdom 
•  Germany, especially North Rhine-Westphalia

Important notes :

•  He may not know that he was adopted. 
•  If he unfortunately does not want contact or information about his origins, I will of course fully respect that.

Please check in your circle:

Do you know a man or remember a boy who

•  is born on 23.09.1960 
•  was adopted through a Catholic adoption agency, or   
•  whose adoptive parents were both teachers, christian orientation, german/ english nationality ? 
-  grew up in Accra, Ghana in the 1960s, attended the German, Swiss school there (enrolled around 1965/66).

Every hint helps – thank you very much!
