Yes, they are on the Internet. It does look like her, but I am not 100% certain. There is one angle that made me doubt.
They look very real to me are they from a french blog originally and does it say marshall might be his real father
It is very possible, of course, that it is so. I must say that to me, however, he lookes neigher like Frank Marshall Davis nor like Barack Obama Senior. He looks very much like the Dunham side of the family, despite different race. But I see no common features with the other two - neither ears, not forehead, nor jawline, nor facial expressions, nor some ineffable affinity you aften see in the photographs of relatives.
