The dying president was carried from Ford's Theatre to William Petersen's boarding house across the street on Good Friday in April 1865.
George Francis and his wife Huldah lived in the front rooms at Petersen's. They were settling down to sleep when a terrible scream frightened them from their bed.

He later wrote a letter to his niece Josephine describing the evening's events:

On reaching the head of the stairs, deponent [Rathbone] requested Major Potter to aid him in assisting Mrs. Lincoln across the street to the house which the President was conveyed. The wound which deponent had received had been bleeding very profusely and on reaching the house, feeling very faint from the loss of blood, he seated himself in the hall and soon after fainted away and was laid upon the floor.
