Surnames: Rilee, Wiatt Classification: Query Message Board URL: http://boards.ancestry.com/mbexec/msg/rw/hAC.2ACE/1217 Message Board Post: My cousin Americus Vespucius Rilee was known as "Mex." The man who gave me my driving test at Gloucester Court House in 1960 was Americus Vespucius Wiatt, known as "Mex." Does anyone know how "Mex" became the nickname for people whose given name was Americus Vespucius ?
