Tessie is a diminutive of the name Teresa, which is of Latin origin and means 'harvester'. It gained popularity in the late 19th century, likely due to its use in the comic opera "La vie Parisienne" by Jacques Offenbach. Tessie has been used inconsistently over time, with some peaks in usage during the early 20th century. Today, it is considered somewhat vintage but is still occasionally used.
"Tessie experienced a gap of four years between her peak birth years."
