Gabriela is the Spanish, Portuguese, Polish, and Romanian form of Gabrielle — Hebrew Gavri'el ("God is my strength"). Gabriela Mistral (1889-1957) — pen name of Lucila Godoy Alcayaga, Chilean poet, diplomat, and educator who in 1945 became the first Latin American author of any gender to receive the Nobel Prize in Literature, "for her lyric poetry which, inspired by powerful emotions, has made her name a symbol of the idealistic aspirations of the entire Latin American world." Worked her way up from a rural schoolteacher in the Elqui Valley to Chile's consul in Madrid, Lisbon, Los Angeles, and Naples. Her face appears on the Chilean 5,000-peso note.
Gabriela 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 Gabriela reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
