Mayo takes its name from Commodore Isaac Mayo, who distinguished himself in the Mexican–American War.[8] Commodore Mayo held a large tract of land on the South River, known in the early 1900s as "Mayo's Neck", that had been the home estate of Captain Nicholas Gassaway, the son of Maryland politician Colonel Nicholas Gassaway.[8] His home, known as Gresham, was listed on the National Register of Historic Places in 1990.[9]
