* ↑ Bouligny opposed Louisiana's secession and refused to resign his seat. He remained in Washington, D.C. during the Civil War. He never retook residency in Louisiana.
* 1 2 Flanders and Hahn were elected in 1862, assuming the seats left vacant after Taylor's resignation and Bouligny's term expired in 1861.
* 1 2 Sypher's 1872 re-election was successfully contested by Lawrence. Lawrence won, but only after the original returns were certified in Sypher's favor. After protracted court intervention, Lawrence was declared elected, but just one day (March 3, 1875) remained in the term.
* ↑ There were so many irregularities in the 1868 election that Congress threw it out. Sypher won the second round against St. Martin.
