ALS, IHi. Charles R. Welles was a lawyer and land agent in Springfield, representing John Grigg of Philadelphia, investor in western lands.
 A St. Louis banking firm.
 Prominent St. Louis business men, Thomas Yeatman and James E. Yeatman were brothers who married the sisters Lucretia and Cynthia Ann Pope, daughters of Judge Nathaniel Pope. The widowed mother of the Yeatman brothers had married Senator John Bell. Since, according to the Dictionary of American Biography, James did not marry Cynthia until May 5, 1851, it would seem that Lincoln here refers to Thomas Yeatman.
