Nobody back then thought Obama would run for President, his mother and grandmother just wanted to make sure he was an American citizen. A lot of people do that, even now. Don't add silliness to the real conversation about a document that every AMERICAN has easy access to. I have an Arkansas birth certificate from 1960 with footprint (very common back then), both parents birthplaces and dates of birth, and a host of other information about where, when, and circumstances of birth.
This is just more BS thrown out there to confuse and divide the electorate.
