Todd County South Dakota

Tripp County now SUPPORTS Todd County, a neighboring county. 

Entrance to Tripp County SDGenWeb 

Todd Co. does not have its own county seat, instead Winner, SD, in neighboring Tripp County serves as Todd's Administrative center. Mission, SD, is the largest town in Todd County. St. Francis, SD is also within Todd's county boundaries.  

This Todd County is rebuilding and hopes to share Pioneer Stories for the Todd website. Any historical insight for either Tripp or Todd is very much appreciated! 

 

A Bit of History: Until 1981 Todd, Shannon (now Oglala Lakota County) and Washabaugh were the last unorganized counties in the United States. Although then organized, Todd County did not receive a home rule charter until 1983. It contracts with Tripp County for the Todd Auditor, Treasurer, and Registrar of Deeds.

Todd County was organized from Indian lands in 1909 after the Great Sioux Reservation was opened to settlement. Because it is an unorganized county attached to Tripp County the county seat is in Winner, SD. In addition, the county lies entirely within the borders of the Rosebud Sioux Indian Reservation.

    Todd County is named after John Blair Smith Todd (1814 - 1872), a cousin of Mary Todd Lincoln. He came to Dakota as an officer in the US Army, but later resigned his commission to become an Indian trader at Fort Randall. In 1861 he became a lawyer and opened an law office in Yankton. He later was a delegate to the US House of Representatives from Dakota Territory and a General in the Union Army during the Civil War.
