Just before he left Illinois for his first inauguration, Abraham Lincoln stopped by a cemetery in Coles County to visit the graves of his father and step-mother. It was Gale Baker's grandfather, John W. Baker, who showed Abe where the bodies were buried.
At the time, the burial sites were mostly unmarked, so Abraham Lincoln carved the initials of Thomas and Sarah Bush Lincoln on a piece of wood to serve as a rudimentary grave marker.If I remember correctly, some other stuff happened between his going to Washington and getting shot.
At least, this is the tale handed down to Gale Baker from his grandmother, Susan D. Baker.
Abraham Lincoln “found those graves and then went to Washington and was shot there,” said Gale Baker, 90. “That’s the story as she told it.” [Link]
