Teresa
Meaning
of disputed etymology, traditionally linked to Greek 'therizein' (to harvest) or the island of Therasia
Famously borne by Empress Teresa Cristina of Brazil, consort of Pedro II.
Name day: September 5 in the Roman calendar of saints (Saint Teresa of Calcutta); the Spanish santoral also honors Teresa on October 15.
The story
Teresa reached America through Spain: the etymology is disputed, maybe Greek therizein, to harvest, maybe the island of Therasia, but the name's force comes from Teresa of Ávila, the sixteenth-century mystic who reformed an entire religious order and wrote some of the most read spiritual prose in Spanish. In the Spanish-speaking world her santoral date, October 15, still belongs to her. The American records show a name that crested at midcentury: strong through the 1950s and 1960s, the very decades when another Teresa, the tiny nun of Calcutta, was building her mission and becoming one of the most recognizable religious figures alive, then easing gently for fifty years to the steady presence it keeps now. The overlap of crest and fame is suggestive rather than provable. What is provable is range: queens of Spain, two canonized saints, and several million Teresas in between.
