Astoria, Queens — historic NYC neighborhood; one of the most ethnically diverse zip codes in the United States; Greek-American cultural center home to Athens Square Park and dozens of Greek restaurants and bakeries; Kaufman Astoria Studios (founded 1920) was the largest US film studio outside Hollywood. Astoria Greengrass — Draco Malfoy's wife in J.K.
Astoria 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 Astoria reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
