Who did Barack Obama grow up with?

Well... Barack Obama didn't have any (actual) brothers or sisters - he had half brothers and sisters (paternal)

He grew up in Hawaii with his mother and father , though they separated when Obama was only two - later divorcing.

His father returned to Kenya and saw him only once before dying in an automobile accident in 1982.

His mother soon re-married and the family moved to her husband's house in Indonesia.
