Tomasa
Feminine · “twin”
The Gospel translates this name for you and then does it again. Thomas is Aramaic for twin. John adds that he was called Didymos, which is Greek for twin. The text is effectively saying the twin, called Twin, in two languages at once — and nobody has ever recorded whose twin he was.

The story of Tomasa
Thomas was almost certainly a nickname rather than a birth name — the twin — and the man's actual name is lost. What survives instead is one scene: he is not there when the others see the risen Christ, he says he will not believe it without evidence, and he is given the evidence. English took a phrase out of that and has used it ever since for anyone who wants proof first, which is a hard reputation for a man whose objection was reasonable. The name went everywhere Christianity did, and Spanish made the feminine in the ordinary way. Tomasa was common in Spain and Mexico for centuries and reached American records with families from both.
Meaning
twin
From Aramaic te'oma, a twin. The Greek text of John glosses it with Didymos, the Greek word for the same thing, which is how we know the meaning with certainty rather than by reconstruction. Tomasa is the Spanish feminine, formed from Tomas exactly as Luisa is from Luis.
