John Randolph Grymes was a New Orleans attorney, member of the Louisiana state legislature, U.S. attorney for Louisiana district, and aide-de-camp to General Andrew Jackson during the Battle of New Orleans.

Jean Lafitte was a French pirate and privateer who operated in the Gulf of Mexico in the early 19th century. He and his older brother Pierre spelled their last name Laffite, but English language documents of the time used "Lafitte". This has become the common spelling in the United States, including places named after him.
