Barack Obama Sr. had a third wife. Her name before marriage to Obama Sr. was Ruth Nidesand. Ruth like Ann Dunham is white. She had two sons by Obama Sr who would be half brothers of Obama Jr. The sons eventually dropped the Obama name and took the last name of Ruth's second husband which is/was Ndesandjo. One of the sons is deceased, but the other whose name is Mark lives in China and runs an internet company and, to my eye at least, bears a resemblance to Obama Jr. He also seems to look nothing like his father Obama Sr.
He lived with Obama Sr. and has talked about the abuse he and his mother suffered at BO Sr's hands.
The other brother of Mark may be fiction.
Check out this thread, explains a lot but start earlier than the end or you’ll get confused.

A lot of research and extremely interesting info on that thread. Very little of the myth of Zero is fact.
Interesting. No doubt, Mark's net contribution to the world far exceeds that of his more famous relative.
Wow, Mark Ndesandjo (Obama) certainly does resemble his half-brother Barack. Maybe Barack doesn’t help out his half-bro George because he figures Mark has more $$$ and he should do it?
