Yes, that book, which is all you have that tries to tell you who his parents were, but with a forged bc you don't know where he came from or who he is.
We do have a little bit more than just the forged birth certificate and the forged book/s. There are the paternal extended family and their neighbors in Kenya who acknowledged barack Hussein obama Jr. as their own during his visit among them, and the family members who came to the United States. It does appear they acknowledge his parentage, rightly or wrongly as the case may be.
