Nope. They’re 0bola’s daughters. The photos showing the striking resemblance are no longer findable with searches.
The research threads on FR told the story. 0b0la is the son of MalcolmX and Valerie Sarruf, born in CA, brought to Seattle when a few weeks old, Stanley Ann Dunham was on and off nanny for some years. If anyone hasn’t read those threads they owe it to themselves to read them. Less than half the research was posted but what was posted is sufficient to see the reality. When people posted info, it was scrubbed right away from the internet so they stopped posting everything.
Oops, didn’t finish one sentence correctly. Sasha and Malia strongly resemble 2 of MX’s daughters at the same age. Clear family resemblence which is not unusual since they are related. Photos no long findable.
