You found what it is now, it was 10 years after the age of 14 in 1961,and that is the rules you go by, and even at 5 years she would have had to have been 19 and she was only 18 when Bozo was born, therefore IF Bozo was born in Kenya, he is not a US citizen.
No, I posted the 1952 law, the one in effect when Obama was born ("not less than ten years, at least five of which were after attaining the age of fourteen years"). Follow the link I gave, or see reply 310.
BTW, the current law requires only two years after age 14 and only five years total.
