I'm not aware of the two pages you mention concerning Lincoln's grandmothers. Your search highlighted the words "president" and "birth certificate," and the article stated that none were used back then. I remember seeing the following recently:

Dwight Eisenhower was asked for his birth certificate when running for president. No birth certificate had been issued when he was born, but one was subsequently prepared and court papers signed by a witness to Ike's Denison, Texas birth. These papers were provided to those seeking the documentation.

See: Link and a 1952 newspaper article reporting it: Link to 1952 article..
