Cyrene (Κυρήνη) is the Greek word for "sovereign queen." The Thessalian princess and huntress who, when seen wrestling a lion bare-handed by Apollo, was carried by him to Libya — where she founded the city of Cyrene and became its first queen.
Cyrene 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 Cyrene reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
