You’d have to go back 55 years. Barack Obama Senior told the Immigration and Naturalization Service on August 31, 1961 that he had a son who was born in Hawaii on August 4, 1961.

worldnetdaily.com uncovered the INS Officer William Woods memo under a Freedom of Information Act request looking into Barack Obama Senior’s student visa records
Along with the memo in Obama Sr.’s file for August, 1961, there is also the memo in Soetoro’s immigration file from 1967 that references Obama born in Hawaii. There is also the Indonesian school record from 1968 that lists place of birth as Honolulu and DOB as August 4, 1961.
And now it's several years later, and he still didn't name a child - much of the information on that form IS WRITTEN IN ANOTHER HAND.
All of which might make one ask, just how genuine is that WOODS MEMO? The handwriting appears similar on both.
And now in April 1964 the wife from whom he is separated IS IN THE PHILIPPINES...imo it's all such a mess there is no way you can use the information from that file to establish just who he might have been married to, or if he had a son born in August 1964.
