Engracia is the Spanish-Latin name meaning "in grace." Saint Engracia (c. 280-303) was the Portuguese-Spanish martyr who refused to renounce Christianity under Diocletian's persecution — patron saint of Zaragoza, where her basilica stands.
Used widely in Spain and Portugal.
Engracia does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Engracia reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
