Sr.’s first name is spelled with a “C” in that clipping.
Only the teacher in Kenya would know...for sure:
...Obama Sr — Index No 3422 — joined the school with his elder brother, Joseph...
Thinking about it...as a boy he went to a Christian school. His name may have been Barack with a ‘c’ because that’s the english way to write the name. I’m thinking he may have dropped the ‘c’ when he returned to Kenya...he was going to be a big man in a newly independant Kenya, and anything that was British was despised...
