According to information published in the New York (NY) Herald on April 3,
1869, William M. Winkler (sic) was nominated by President Grant to be the
postmaster in Columbus, Indiana. (See p. 3.)
According to the Ft. Wayne (IN) Daily Gazette and the St. Joseph (MI)
Herald, William's surname was Winkley, not Winkler. (See p. 1 and 2
respectively.)
