Bismark Kyei Obeng is one of the four children of Nicholas Kyei Obeng and Janet Ackom. The former was a worker at the Stool Land Administration at Agona Swedru. The couple lived together until the mother developed a mental problem and was taken away to live with her mother for treatment at Dunkwa-on-Offin.  All the children and their father stayed at Agona Swedru with the exception of their two year-old brother who went with the mother.

Unexpectedly, after a short illness of jaundice, the father died and the children had no one to care for them. The Assisim church therefore divided the children among members to care for them in the short term. A few weeks after Nicholas’ death, the Assisim Minister, (who was catering for the oldest of the children, Beatrice), made a request to the Village of Hope for the admission of the children into residence to ensure a meaningful future in terms of training and education. 

However, in view of her age and lack of enough space, Beatrice, the oldest child could not be admitted.  Thus, only Bismark and his sister Stella were admitted with the hope of helping Beatrice and the younger brother still living with his mother in any way possible.
