Natalie is from the Latin natale Domini ("birthday of the Lord," Christmas) — first used as a Christian baptismal name for girls born on December 25. Harvard University BA in Psychology (2003). Natalie Cole (1950-2015) — Grammy-winning singer; Unforgettable... Natalie Imbruglia ("Torn" 1997). Natalie Maines (Dixie Chicks/Chicks).
Natalie 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 Natalie reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
