I think his Kenyan Grandmother is still alive. I won't swear to it but I have never heard that she died. I heard while he was POTUS that His American Grandmother in Hawaii had died!! I think she may have been his Great Grandmother . I don't remember him ever mentioning his Mother's Parents in Kansas!!
Also there used to be a big Billboard at the entrance to their City in Kenya, that said Barack Obama Son of Barack Obama SR was President of the United States, and that Billboard was taken DOWN when all of the scandals came up,that he was involved in!!
