Grandma can't travel? What language or languages does Grandma Sarah speak? And where is the evidence that she does not speak Swahili?
Swahili, Kiswahili in that language, is spoken by the majority of Kenyans. Many also speak English. She most likely also speaks Dholuo, aka Luo, the language of the Luo tribe.
In fact, it turns out their is some indication that Grandma Sarah does speak another language other than Luo.

Why Obama Wept for His Father

When he met Dorsila, the youngest child of his great-great-grandfather Obama, who was in turn the great-great-great grandson of Owiny, the legendary Luo warrior whose armies defeated the Bantu nine generations before the white man came to Kisumu, she was startled when he pulled out a Bic to light his cigarette.
...
Dorsila, who spoke only Luo, listened nonetheless as Obama and Auma's "Granny", the same step-grandmother, now in her eighties, who Senator Obama and his wife and children met with in the summer of 2006, shared the oral history of their family.
Thus the conversation must have been in some language other than Luo. Given that most Kenyans speak Swahili, at least at some level that would seem to be the most likely language. Swahili is one of two official languages of Kenya the other being English. Most literate Kenyans, around 85% of those over 15, about 80% for women, do speak Swahili in addition to their tribal language.
The affidavit in Berg's suit claims that it was taken in her home, in her home village. It got the name wrong. And every bio of his grandmother out there agree on at least one thing, she speaks Luo, and a few words of English, and nothing else.
Thus the conversation must have been in some language other than Luo.
One would think, since Obama doesn't speak Luo or Swahili.
