Wilkin County is a county located in the U.S. state of Minnesota. It was originally established as Toombs County on March 8, 1858, named after Robert Toombs (1810-85) of Georgia, who had been a member of Congress, 1845-53, and was U.S. senator, 1853-61. Mr. Toombs became a leading disunionist, then a Confederate secretary of state in 1861, and later was a Confederate general. In 1863, the county was renamed Andy Johnson County after President Andrew Johnson and to disassociate with Mr. Toombs. The county again changed its name to Wilkin County in March 6, 1868.
