In Louisiana, the proper form of address for a sheriff is "Sheriff [Last Name]." For his wife, she is typically addressed as "Mrs. [Last Name]." If the sheriff holds a higher rank, such as "Colonel," that title can also be used. When addressing them collectively, you might say "Sheriff and Mrs. [Last Name]."
