Or the information provided to the Department of Vital Statistics was false. If so, that points to a false application. Possibly with the wrong date given.
While it's not totatly impossible that Stanley Ann would travel to Seattle, from wherever, in the month following the birth of her first child, where both University of Washington records and the recollections of a friend, place her in late August of '61 in the latter case and mid to late September in the other, it seems unlikely. Unless "wherever" was very close to Seattle, that is not requiring a long plane ride or boat trip. Now there woudl be no reason to "fake" being born in Seattle, or anywhere else in Washington state. But Vancouver BC is "close", and it might be worthwhile faking birth in Hawai'i to disguise birth in Canada, just to have the child recorded as a US Citizen.
What if one of the three Lefforge children was born around that time?
From what I have read all were under the age of seven at the time, perhaps one was born during that time and the part about Mr. and Mrs. Barack Obama was pasted over the Lefforge families announcement.
