Thressa, of Latin origin, means 'to rejoice'. It's a unique and charming name that has been used infrequently throughout history. In literature, Thressa is often depicted as a strong-willed and independent character, such as in the novel 'The Mysterious Island' by Jules Verne.
"The name Thressa had a modest start with 6 births each in 1888 and 1890, but gained traction around the turn of the century with consistent appearances between 1908 to 1927, peaking at 27 births in 1916. However, its popularity began to wane by the mid-1930s, with a significant drop after 1959, and it has remained relatively uncommon since then, with only 5 births each year from 1978 onwards."
