No, because Stanley Ann had not lived the requisite number of years after the age of fifteen in the states. I think it is five, and she was 19.
Was she not born in the US?
The rule at the time of Obama’s birth was 5 years after age 14. Stanley Ann was born in November and Obama was born in August, so she was 18 years and 9 months at the time of his birth. That makes her clearly ineligible to convey citizenship on Obama, regardless of her place of birth.
It’s “five years after the age of 14”. she had to be 19 to confer citizenship, but was only 18 when 0 was born.
