“There is a record in the safe at the Maseno School of an older brother named Joseph Obama, who attended the school until 1951.”
A record number is given for the card of BHO SR, but NOT for the claimed brother. In a card record system like that, as they clearly stated, each student has a card and on the information for the student is summarized on that card.
There are no quotes around the comment about the brother so it is not indicated that the comment was a verbatim statement being claimed to be read from any record card.
It the other brother existed and was not just a cousin with the same tribal name, he would have his own numbered card but no such card or card number was referenced as the source of the claim that the brother left the school in 1951.
This story at the school is a hearsay account written by a newspaper reporter. He claims to have seen documents but provides no images. No older brother, Joseph, exists anywhere that I have seen in all of the extensive family coverage and interviews of the Obama clan.
But Malik isn't leader of the clan, he didn't inherit. Sarah, wife of Onyango is recorded as telling Malik, no, he couldn't build a mosque when he wanted to, and if he didn't behave, he would be removed.
There's some reason the elder brother has been kept from view, he's always in the background, he wears the cap and carries the whisk which shows his position as leader of the clan. And he could only be that, if he was the eldest son of Onyango.
Passport shows birth year as 1934, but he's buried as born in 1936?
He doesn't look like he's too impressed with his US relative, does he? Maybe he has good reason, and that's not the happy family photo-op it was supposed to be, either.
