Jesse K. Dubois 
My acquaintance first began with him in 1836. He was a member from Lawrence and Coles. Our friendship has continued and strengthened. When I first saw him he was a slim handsome young man, with auburn hair and sky-blue eyes, with the elegant manners of a Frenchman, from which nation he had his descent.
You may safely confide in him and in all he would advice you to confide in.

Neither fragment is dated, but the second is described as being in a letter of recommendation written while Lincoln was a candidate for the presidency. No further reference to the documents has been found.
