The conservative parishes: Jefferson, Grant, Union, Lincoln, Jackson, Webster....

Staunchly Democrat: Orleans, Avoyelles (birthplace of Edwin Washington Edwards), Jefferson Davis...

Kinda defies the Dixiecrat theory. One of the most conservative areas of Illinois is Lincoln, which has been Republican since the Republican party was founded. It became incorporated by December 1860.

Overall, I would say the most Republican parishes are St. Tammany, Lafayette, Ouachita, Caldwell, La Salle, Bossier, and Jefferson.
