Milagros is the Spanish word for "miracles" — referring to the Virgin Mary as Nuestra Señora de los Milagros (Our Lady of Miracles). One of the most beautiful Marian Spanish names.
Milagros is widely used in Spain and Latin America.
Milagros 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 Milagros reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
